• Problems of the inverse tangent function

  Hello

  I try to use the function trigonometric "arctangent", but it does not work because I think that it should. I want to change a gradient at an angle, normally on a calculator, I use height divided by the length and press the tan ^-1 (inverse tan) function and get the angle. For example, the inverse tangent of 1. 45 (degrees) If I use the inverse tangent function in Labview 2010, I get a completely different = 0.7853 result... I use it wrong or the function does not work correctly.

  I've attached an example so that you can reproduce the result. I also had a similar problem with sin and cos in the formula of node structures.

  Thanks for any help you can give,

  James

  Hi James

  I have not seen your VI. I know, given out by the trigonometric functions in Labview is expressed in radians. You need to radian to degree conversion for the response under 45.

• HP 48gii: hp 48gii trigonometric function help

  Hello

  I'm not sure what I did to my calculator, but instead of giving me the answer for a question of trig (for example cos 40 = 0.76604444311) happens only with cos (40).

  I have it configured in Deg, XYZ, DEC, IR = 'X '.

  Any help to give me answers would be gretaly appreciated.

  Hello

  Your calculator is symbolic and Exact.

  In the MODE menu, select CASE (F3) and put a check mark next to or the two '_Numeric' and '_Approx '.

  For more information on these and other modes of CASES, see Appendix C of the Guide of the user

  See also the advanced user's reference manual.

  http://h10032.www1.HP.com/CTG/manual/c02836298

  Appendix C flags - 3 and-105 describe the symbolic modes and about.

  (section 1 provides an introduction to RPL programming
  section 2 gives examples of programming and

• 50 g: HP 50g is not right graph of trigonometric functions

  Hello, trying to graphical things like Y = SIN(X) and Y = COS(X), Y = TAN (X) mode degrees I get graphics and table results

  that cannot be right.

  Instead of a signal sinusoidal, all I get is an oblique line very shallow. For all cos there is a line above the x-axis. The tangent is the same thing as Sine.

  To put the calculator in Radians mode it does very well, but it is in radians.

  I tried the same parcel on my HP48G using the regular tracer and mathtools, but I always get the same things.

  Is there a setting I have hurt either I put something in incorrectly? Using a Ti-83 (awful piece of tat) it works fine. However, it is part of the worst graphics calculators that I've never used, so I don't want to use it.

  If all the other details are necessary, I can try to give them. Thank you.

  Is there a setting I have hurt either I put something in incorrectly?

  The problem is probably caused by incorrect setting "window."  Press down the shift to the left and holding it down, press the F2 key (see 'WIN', which stands for 'window').  Make sure now the H-view (view horizontal, that is, the values of axis x on the left and right of your screen edges) are reasonable for the degree path mode.  Try something like-360 and 360, for example.  This would correspond to a 'window' of - 2pi + 2 pi in radian mode.

  Hope that helps!  DISCLAIMER: I do not work for HP, I'm just another passionate about Calculator HP happy.

• Using trigonometric (sine, cosine) functions in Acrobat Scripting

  Hello

  I inherited a form of a colleague and would like to make some changes in one of the fields of output using a formula that includes arc sine and cosine functions. All scripts that are attached to the form fields use FornCalc but I couldn't find the arc sine and cosine functions in FormCalc. The manual mentions that the scripts associated with the form fields can also be written in javascript and research online, I found that this javascript has a function math.cos() and Math.asin (). My problem is that I don't know anything about javascript programming (and very little about FormCalc and XML) and would appreciate much help on how to write a script JS using Math.cos and Math.asin. The script is associated with the form field and the values used in the trigonometric functions are declared global variables and form using modified elsewhere FormCalc scripts. I use adobe acrobat 9 pro Presentation.

  Thank you

• can someone explain this code pls!

  speed * =. 98;
  (x = Math.sin(_rotation*(Math.PI/180)) * speed *-1;
  y = Math.cos(_rotation*(Math.PI/180)) * speed *-1;
  If (! _root.granica.hitTest (x, FLF, _x + y, true)) {}
  _x += x;
  FLF += y;
  } else {}
  speed * =-. 6;
  }

  Granica root is an instance name that I used, it can be something else...

  I think that shat speed is a variable or sth, cus I've already used it previously in the code and I guess now I'm just set...

  but someone pleasee help out me by explaining what part of the code, we hear what may...

  BTW I also think it has something to do with the trigonometric functions, that sin and cos...

  TNX in advance

  speed * =. 98; / / decreases the speed - IE, this object slow down gradually
  (x = Math.sin(_rotation*(Math.PI/180)) * speed *-1; / / these two lines cause the object to move in the direction of _rotation, rotation of the object
  y = Math.cos(_rotation*(Math.PI/180)) * speed *-1;
  If (! _root.granica.hitTest (x, FLF, _x + y, true)) { / / This checks no imminent collision with _root.granica }
  _x += x; / / If there is no collision that would happen, advance to this post
  FLF += y;
  } else {}
  speed * =-. 6; / / If there is an imminent collision, not to move on this loop inversion with a lower speed

• base newspaper Scientific Calculator

  Hi guys,.

  I searched online for documentation on the basic button y log in scientific calculator iOS but I could not find.

  

  What is it?

  What is the inverse logarithmic function?

  If so what base? Base 10, 2 or e?

  Thanks for the help.

  This isn't an inverse logarithm, it is one logarithm using any other basis as the existing buttons for base 10 or base 2 logarithms.  The "y" is any basis you want to use for the logarithm.

  Suppose you want the logarithm of base 4 of the number 12 (i.e. log4 12).  The keystrokes you would use would be:

  • 12
  • Logie
  • 4

• Agilent 4263 B time-out error

  I changed the model of implementation of Agilent 4263 B to include three additional screws (seen on the bottom row of the image included). I get a timeout error (GPIB-213, ignored measure opening request for another measure was already underway) to initiate her block, the block right in the bottom line. What causes this error and what can do about it?

  

  A bit of a guess, but if the: TRIGONOMETRIC function triggers a measure then the error is probably correct that a measure is ongoing and probably indicates that the function MEAS READ has enough intelligence to wait as the fill.

  If you try to do is to measure different parameters, you need to move your new block of code after the function MEAS READ, set the FREQ and measurement, and then call: TRIG again, instead of the function INIT to trigger another measure.

• implementation of flight collection in 2D walk

  Hello

  I try to draw the market of levy flights in a 2D space to get a similar path like this.

  https://en.Wikipedia.org/wiki/L%C3%A9vy_flight

  I found that I can use the inverse Gamma function to generate the gamma distribution of the random number I can multiply the coordinates (x, y) for every new step. First of all, I want to check if this is appropriate and feasible with Labview.

  I found this rapprochement that might prove useful in wikipedia.

  • If then (distribution of Levy)

  I made a draft of the Vi and I would be very grateful if someone can help me or post comments.

  Thank you

  Zied

  Seemed like something fun to try (one of the few remaining sections in the book of Mandelbrot set that I've not yet recreated), I use the Inv-normal Distribution instead of the Inv-Gamma to get distributed Levy steps.  Choose a random between 0 and 2pi and length angle of distributed sample no.

  

  

• How can I draw a line at 40 ° c in windows7 paint

  Hello

  I use the part of Paint in Windows 7 and I would like to know if I can draw lines with angles varoiuse 30 and 60 degrees

  Best regards, Nigel Terry

  Unfortunately, the painting doesn't have this feature.

  The best we can do would be to select the grid and the leaders of the view tab, in the paint can use base for a right triangle trigonometry - see:

  Trigonometric functions (Wikipedia) .

  The foregoing would be very tedious, time-consuming and probably too imprecise.

  A better option would be to seek a 3rd part of the program, possibly a design (CAD) program assisted by computer. You will need to consider as you know what exactly it is you are trying to reach.

• trigonometry calculations

  I'm new on this and just starting to get my head round all this, is it possible you can do calculations of trigonometry like TAN, ATAN or Sin in excellent under a shape just like the addition or subtraction.

  for example = $H$ 1 * ATAN ((COS (C10) - 0.15116) 1/Tan(x) (C10))

  see you soon

  JavaScript has support for trigonometric functions (all in radians). Just do a google search for "trigonometric functions in javascript" and there will be a lot of success.

• HP FIRST: function Inverse on the question of the HP Premium

  Hello

  I was wondering if anyone new how to find the inverse of a function expression on the HP Premium algebriac.

  This can be done on the Casio Class Pad using the inversion function. Watch the video link below.

  https://www.YouTube.com/watch?v=8jSKf8OJaW4

  So may my question a similar thing is done on the FIRST HP.

  Concerning

  Arthur Rappos

  The forum said that my image upload is "pending approval".  I hope it shows up soon.  If not, here's a link to it on my web server: http://holyjoe.net/images/isolate.png

  In the meantime, you can find the inverse function of almost no matter what there simply by solving this equation of x using the command solve in CASE.  This is sometimes referred to as "isolation x".  For example, if y = 1 + 2 / x, you can find the inverse function in case of premium by typing this:

  Solve(y=1+2/x,x)

  This isolates the x the other side of the equation, which gives us x = 2 /(y-1), which shows the inverse function, we were looking for.

  The command solve can insulate almost any variable from almost any equation.  It is very powerful.

• Where is the inverse function in Windows 7 paint program?

  In the new program paint in windows 7 How can you reverse the image? CTRL + i no longer works and I can't find the function. This is a feature that I use extensively to create complex abstract images and I am wondering where is this feature?

  Your not fake - they forgot to put it in.

  New windows paint is actually a program .net - the old paint bitmap has completely disappeared... and that includes the actual executable file for her...

  mspaint.exe is now definitely a totally different program - so, even if you try to copy the old mspaint.exe in the system32 folder it will clear a new one that is named the same.

  I do not know what dependencies had the old mspaint.exe (some dll somewhere - but I don't think - it's a program simple such as Notepad, doing all the way back in win3, changed over time.

  If you have a copy of XP or similar copy the file c:\windows\system32\mspaint.exe to your PC and rename to something like XpMSpaint.exe, place it wherever you like (my preference is for the system32 folder) and create a shortcut to it.

  BUT...

  I would recommend going for a better bitmap editor...
  Them is actually a .net adobe basis as app is completely free and designed specifically for windows http://www.getpaint.net/
  or Inkscape is also very good and very easy to use. If you want even more professional free alternative to Gimp is another (but it's hard to use if your opportunity to "common" way of doing things)

  .. but once again the best option is Corel Paint - you can either buyit grouped for about $50 US with corelDraw! (highly recommended) or on its own for as low as $19,95 (which is a riduculous price seen CorelDraw is the principal vector arts program on the planet.) (users of adobe will be saying the opposite - but thyre all artists are not)
