HP 50 g equation writer

can someone help me please whenever I try to write an equation into the equation writer beggening with a negative number, nothing happens

FOR EXAMPLE

redshift > EQW >-> 5 > + > 2

the result would be 5 + 2

nothing happens when I press the button "-" before the 5th

Hello

To enter a negative number, use the +/-key (key no. 7 above).

I hope this helps.

  • HP50g equation writer

    I'm trying to reproduce the task of moving an algebraic of the display to the writer of the equation. The HP48s/sx was capable. I looked through all three PDF files that are provided on the CD with my calculator.

    I tried to copy some algebraic time in normal view, goes to the author of the equation, then stick but can't get that to work. Someone knows how to do this or there HP decided that was not a function that should be retained?

    Hello

    As you ar familiar with 48 s/SX, I assume you are using the 50g in RPN mode.

  • Questions write equations to existing variables in Hp 50 g

    Hello

    I'm studying for the exams in June and I'm writing long equations in my HP (algebraic, std, degrees, rectangular), but whenever I try to write a new one, if there is a variable with the same name, it displays its value, not the name I typed. I know this may sound confusing, but here's an example:

    • I do an exercise and I'm saving the following equation: A = B + C (for example).
    • I use it and I begin a new fiscal year.
    • In this exercise, I save the equation: B = C * E * R/T, but when I try to save in a variable, it changes the letters B and C for their values. So if I want to solve an equation with different values of B & C I can not because they do not appear on the equation 'solved '.

    I know I can clear all variables before writing a new equation, but it's a pain in the ass, is there a good way to do it?

    Thank you.

    You not need to use this method to purge.

    your first equation must be entered this way: (use equation writer or the command line)

    "" A = B + C ".

    STO > "EQ1".

    (for this example, when "the equation" was performed for the equation A = B + C, a 8 value was entered for 'B' and a 9 value was entered for 'C')

    NOW THE IMPORTANT STEP...  (this step is not necessary in RPN mode... In RPN mode, simply enter the equation using EQW or line commmand is also normally done)

    When you enter the second equation, this can not be easily done using the equation editor.

    To easily fix the problem to get into the second equation and keeping variables unadulterated into the equation, you must enter the equations on the command line.

    Start with a single quote... This indicates the 50G an equation will be entered

    When you enter the variables that were previously used... put single quotes around these variables...

    for example:

    "« B » = « C » * E * R/T"

    Press ENTER

    your screen should look like this:

    now

    STO > "EQ".

    Enter "The equation" and the variables used before are shown with their values pre-filled... but all the variable can be changed...

    NOTE NOTE: If you want to change the equations in this window, use the right CHOOS button, select another equation in this example, it is called EQ1... (The CHOOS softkey is available only when the equation is highlighted as shown in the screen above)

    Press CHOOS, and see the following:

    Select EQ1 and press F6 (OK)

    now, the screen changes:

  • HP 50 g EVAL error: internal error CASES

    I'm trying to use the EQW Solver to solve a formula that uses the sigma notation.

    n
    Σ (a + i (b - a) / n)(b-a)/n.
    I have = 1

    When you try to solve for the proof I get the indicated error.
    Does anyone know why such an error occurs? Is there a problem with the symbolic notation or a bug in my HP 50?

    When you enter the initial problem of the summons, you must enter an algebraic equation.

    If you use the equation writer and enter the summation symbol as shown:

    the 50G will not enable the lowercase letter "I" entered as the summation variable (where the arrow is at in the screenshot above).

    Also, FYI, some branches of engineering also recognize the lowercase letter 'j' as the symbol of a complex variable instead of the letter 'i '.  It has to do with the bad hand writing and the letter 'i', similar to the lowercase letter "L", etc... so you can avoid using 'i' tiny or low case 'j' in the equations at least that specifically refers to a complex number ('i' tiny for the equations of 50G only).   However, in your present mathematics classes it may not be of concern.

    If I understand the mathematical order of precedence indicated in your displayed equation, with some necessary changes to the variable of summation your equation should look like the following:

    Enter this equation in the battery, then press EVAL.

    If you want a different form of the same solution, run FDISTRIB

    set the CORRECT mode and do of course-2 flags and flag - 3 is deleted (constant-> symb; function-> symb) for this equation - see the reference to advanced for the function ∑ users.

  • Reactance frequency-dependent in the definitions of materials

  • FrameMaker-&gt; XML-&gt; FrameMaker questions

    Hello

    I have currently about 150 pages fm submits, that were originally unstructured, but I managed to make a structure of work for her. There are mainly paintings, which have references, images, graphics, tables and internal stuff, so all normal technical document. Reason I'm structuring it and what about XML is that we have another file XML where we will add data in this document, and currently, it is done by hand and we want to do it my machine. These things are done by the magic of programmers who can better c-related speaking in tongues English.

    I can make the XML of this fine, so that the XML that is created is valid and structure looks like, it is very well copied as XML. Graphics, images and internal tables are currently inside anchored like graphics frames, since they were something similar in the informal document and read/write rules that transform images EPS, because internal tables do not work like SVG, I prefer otherwise, because it is also the XML and anchored frames have some links referring to other parts of the document. SVG would be also easier to manage in programming (or so I think) as the EPS. If anyone can think of the best way to do this, I'm open to suggestions.

    Question now is when I opened this created XML in FrameMaker, it loads first half-hour (computer is Intel T2500 2 GHz, 2 GB of RAM, computer laptop XP Pro SP3 and FM is version 10), then displays the 9 error pages records concerning 'framemaker cannot insert table (cell) at the current position cell' and then document appears as 600 to 1000 pages 'masterpiece' where 150 pages seems normal but after this first page If displays of new and tables is presented as a column in the page. It was suggested that if the file is created by FrameMaker, FrameMaker it would open normally, but apparently this is not the case.

    Reading/writing-rules currently look like this: (if it is useful at all)

    {"Table" element

    is the table fm "Table" element

    }


    element {"TableHead"

    is the fm "TableHead" table header element

    }

    element {"TableBody"

    is part of fm "TableBody table body."

    }


    element {'Row'

    table fm line item is "Row".

    }

    element {'cell'

    is fm "Cell" table cell element

    }


    cross reference fm 'HRef' element's "HRef";


    element {'Row'

    is the element of row in table fm 'ROW '.

    }


    'Cell' is fm "CELL" table cell element


    element {"Graphic"

    is the graphic element of fm;

    writer anchored frame {}

    export to file ' $(entity) .eps "as"EPS ".

    specify the size in pt;

         }

    }


    element {"Equation"

    is fm equation element.

    export equation writer to file ' $(entity) .eps "as"EPS ".

    }

    There are some things that might look odd for some people. There are a few conditional text in FM submit and without rules as

    'Cell' is fm "CELL" table cell element

    XML is not valid against the DTD.

    I'd appreciate any help. I can also provide other files here, but due to NDA reasons, real document is no-go, but I think that if the structure is needed to see, the DTD is very good.

    Ian, Russ,

    As you probably know both, it is perfectly acceptable to have multiple rules read/write for a type of item. In this case, the rules include:

    element {'Row'

    table fm line item is "Row".

    }

    element {'Row'

    table fm line item is "ROW".

    }

    or

    element {'cell'

    is fm "Cell" table cell element

    }

    'Cell' is fm "CELL" table cell element

    The first pair of rules said FrameMaker when it creates XML, FrameMaker and PLACE items that both are output as an XML line items. The second pair of rules said the items FrameMaker and CELL are saved as XML as cell.

    When there are several relevant mappings, FrameMaker uses the first to appear in the rules of r/w. When is the reading of XML documents by using these rules, he could map a line XML line or LINE item and a cell to cell or CELL. Since mixed case of these two rules version appears before the version all uppercase, when reading XML, FrameMaker elements with the same name as the XML namespace it creates.

    Ejlamsa,

    Your FrameMaker EDD has both row and LINE (cell and CELL)? If this isn't the case, you can remove rules for the types of items you don't use.

    Insofar as the error messages and the wrong document when you open XML, Ian is quite correct that FrameMaker needs to know the number of columns there are in the table. If your DTD does not yet of this attribute, the simplest solution is to add a. It is possible using a plug-in or script to create columns as needed, but it's a lot more effort.

  • Write an equation in JavaScript for a loan agreement

    Hello

    I can't put an equation in the form of JavaScript. I'm trying to calculate how much a loan will cost a fixed interest for a period of time.

    So we have the equation: estimated current value = (1 + InterestRate) ^ LoanTerm

    With the fields in my form, I think that it would look like this: Ttl = AmountFinanced (1 + rate) ^ NumberofPaymentsRow1

    My JavaScript for my form named "Ttl" currently looks like this: AmountFinanced * Math.pow (1 + rate, NumberofPaymentsRow1)

    -Unfortunately, it does not return a value, and I'm out of ideas. I don't know where I'm wrong and any help would be appreciated.

    javahelp.png

    You get the errors arise?

    Have you checked the JavaScript console to find errors?

    The custom JavaScript calculation option requires the complete JavaScript coding and is not a front-end process collection of treatment parameters as the first calculation of two options. You must write the JavaScript complete not one shortened.

    JavaScript is an object oriented language, you will need to connect to a domain object until you can access the value property of the field. You must use the 'doc.getField (cName)' method to acquire the field object.

    You must also specify the target or object where you want to place the result.

    Event.Value = this.getField("AmountFinanced").value * Math.pow (1 + this.getFieldI "spleen '") .value, this.getField("NumberofPaymentsRow1").value);

    Note that JavaScript is case-sensitive for domain names, function names, variable names, etc.

  • The first (emulator) HP: HP Premium differential equations

    Hello

    I'm looking a calculator with AC for my electrical engineering studies and just tested

    the first emulator to get a first impresseion.

    But while testing its features, I got some results of unexpectet on differential equations,
    that I would be confirmed on a calculator of real world.

    A simple as equation y' = x

    CODE: desolve (diff (y) = x, x, y)

    wait-> x ^ 2/2 + C

    First HP-> 1/2 * (x ^ 2 + 2 * C).

    The result is correct, but nobody would write it down in this way, nor would one solve it how works the first.

    A little more difficult equation could not be resolved by the premium: 2 x ^ 3 * (1 + y ^ 2) = y'

    CODE: desolve (2 * x ^ 3 *(1+y^2) = diff (y), x, y)

    wait-> y = tan (1/2 * x ^ 4 + C).

    First HP-> could not resolve the implicit equation

    It is not an implicit equation, the two WolframAlpha (iOS) and CASES of TI (iOS) could also resolve this one)

    And last but not least: y' * sin (x) = y * ln

    CODE: desolve (diff (y) * sin (x) = y * ln (y), x, y)

    wait-> y = e ^ (C * tan (x/2))

    First HP-> y = e ^ (sqrt (cos (x) ^ 2-1) / (C * cos (x) + C))

    I don't know what made the CASE here, but there is no reason to use the Pythagorean trigonometric identity.

    Would be nice if someone with a premium could conifrm/refute these results or tell me what I've done
    evil.

    Hello

    The latest version of premium can solve your 2nd test case (desolve ((2 * x ^ 3 *(1+y^2)) = (y'), x, y))

    However, the results for 1 and 3 test cases are the same that you tested.

    I will pass the info to the person who develops the CASE and if all goes well he will be able to improve it.

  • HP 40GS systems of linear equation with parameters

    Hello

    I'm in the learning curve of the HP 40GS - a very interesting tool.

    Is it possible to solve systems of equations with parameters, for example:

    A * X + Y = 2 * 12

    5 * X - 3 * A * Y = 5

    HP 50 g, this isn't a big deal, but with HP 40GS I don't have an idea so far.

    If this is not possible, it will be possible if I have a third equation (so 3 equations in 3 unknowns)?

    Thank you very much in advance,

    Joachim

    P.S.: So far, I feel very comfortable with the HP 40GS and menus!

    ----------------------------------------
    I am not a member of the HP Calculator development team - unfortunately!

    Hello

    now, I found a way to calculate the systems of equations with symbolic coefficients:

    See the document: http://www.hp.com/ctg/Manual/c00829737.pdf to page 346ff

    With the command 'linsolve', it is possible to calculate with more unknown than equations.

    I hope this helps anyone with the same or close problem.

    Have fun with your calculators and do not hesitate to write other ways of calculations.

  • My document word with equations is broken

    I am currently using Microsoft Word 2011 for mac. I am running OSX Mavericks release 10.9.5.

    The problem is often trying to develop a paper of mathematics all pictures and equations jumping around in the document, without even clicking on them. I can have a perfect layout, keep writing on the next page and when I scroll up once again, some of the text has disappeared, the images are a mess and equations moved. It may be important to mention that I use the function "automatic ball/number/letter" (or whatever it is called in English). It looks like this:

    (Support more with the language - I'm Danish)

    As you can see here, the document appears as it should and most importantly: equations are in the middle where they are supposed to be.

    Look now what happens if I move my mouse over the text and scrolling down and back up again once:

    As you can see, the equations are passed:

    And if I try to edit the document, what happens:

    Some of the text is now completely gone!

    This is a really huge problem for me because I often write math assignments and to spend hours to everything put in place when I'm done with the result looking terrible.

    If anyone can think of a solution, it would be much appreciated.

    Thank you in advance-

    You will have more luck asking in the Microsoft forums.

  • non-linear system Solver more equations than unknowns

    Is it possible to solve a nonlinear system with more equations than unknowns in LabView. I do a triangulation and data from several sensors, so I'm able to write 6 equations in order to get the 3 coordinates (x, y, z) as a solution. In LabView, I was able only to solve a system of 3 equations with this 3 unknowns, but I would use the set of 6 equations in order to obtain a more accurate solution, given that some measures can be noisy.

    Thanks in advance

    You can use the non-linear curve code to solve this problem. Consider the following system:

    3XY + y - z = 12

    yx + x ^ 2 + z = 12

    x - y - z = - 2

    Arrange to get 0 right side. x, y and z are the paramneters to be in shape. The entrance to the curved Fti.vi Y non linear will be an array of three zeros. Initial settings will be an array of three values, for example [1 1 1]. An example is attached.
