Calculate the tangent arc of 0.12 degrees

Knows ActionScript really get mad sometimes.

I'm trying to calculate the arc tangent of a number.
I use the following code:

arctg_mi = Math.atan(Math.PI/180 * 0.12)

As you can see, I need calculate the tangent arc of 0.12 degrees. Problem is that it just cannot be done. I'm not an expert in mathematics, but it seems that the radian system does not behave as a system of degrees when it comes to the tangent arc.
I used the Windows Calculator, and tangent arc of 0.12 to system of degrees is about 6.84, which is just. But when I go to the radian system, then convert 0.12 degrees to radians and then try to calculate, I get an incorrect value. Totally wrong!
Solution? I'm so stupid that I missed a few ordinary procedure in all this, or these two systems are not comparable.
Or do I need to convert the value that I return to the system of degrees somehow?

The best thing to do would be to move the Flash to the system of degrees, but which does not, if...

Help, please...

It comes out to 6.84 in Flash, if you do it right. First, degrees
by radian is 180/Pi not Pi/180. And you want to get the arctangent of the
value, that comes out in radians, then convert to degrees - you don't want
take the arctangent of the degrees...

So:
var degreesPerRadian = 180.0 / Math.PI;
trace (Math.ATAN (0.12) * degreesPerRadian)

6.84277341263094

  • Calculate the % of 'Make with Warp' indication / ARC?

    Hello community,

    I translate a menu German so I hope I get things right.

    I would really like to know how to calculate the percentage of the CRA found in the options function if you choose the command OBJECT > MAKE WITH WARP > ARC of STYLE-> bend /(curve?)

    Bildschirmfoto 2015-01-06 um 13.09.09.png

    Why?

    I want to print a long line straight line on a piece of paper, cut it out and then paste this line into a simplified conical water glass.

    What is going on?

    The line appears folded due to the deformation / curvature of the object from its tapered.

    What then?

    With the option to MAKE WITH WARP I can compensate for warping/bending of printing in - / decrease the percentage of the warp/curvature.

    So far, I have found the percentage just by trial and error print lines with different curves which is a LOT of work (and paper), with the lines on the glass to see who looks all right.

    I was hoping someone knows how the percentage is calculated... In the photo above: what does the 25% stand for... ?

    Any ideas?

    Best regards and a happy new year!

    Carl,

    In a certain vagueness, the % of Warp expresses the angle between the part of initially vertical end in % of 180 °.

    In other words, inspire and keep original width of base, an arc (set) is built where the arc (set) has the width of origin and forms an angle of 180 ° * 100/Warp % of the corresponding circle.

    When you have a line as in this case, it's just the width of the line, and there is no set of arcs.

    25% in an angle of 45 °

    50% is an angle of 90 °

    75% of an angle of 135 °

    100% an angle of 180 °

    So if you know the angle spread, you can easily calculate the % of Warp, dividing the angle of 180 ° and multiplying by 100.

    This angle depends on the angle at the top of the cone, the size of the cone, and the diameter of the line rate.

  • How to calculate the degree of rotation of ticks

    Hello again,

    So with a lot of help I got here, I was able to move all the way to learn how to do my work digitally instead of with an old camera.

    In my last discussion, I learned to make the tick marks with copies and rotation.  Now, my question is, how is the rotation calculated if A) I get the placement right tick brands, especially small ones because there are so many and B) how calculate the degree of rotation so that I have the right amount of space at the bottom of the gauge/dial?

    Here is a picture to show what I'm asking:

    rotation degree.png

    I know how to get the tick big brands and small graduations, if I had to place it evenly around the entire circle, I know how to do this too - but since I'm putting around some of the circle (although always evenly) I'm lost.  I can understand only the space of hit and Miss calculations and that takes too much time.  I also need to know how to rotate the whole thing by obtaining space open as shown below.

    Thanks for your help!

    Well let's say you want a gap of 90 °

    and need for 100 points. then: 360 ° - 90 ° (270) / 100 = 2.7 copies up to 100 angle 2.7

    and need 20 points then it will be 270 / 20 = angle 13.5

  • Calculate the maximum value of the sub-table when creating using a structure of case and records the shift

    I have two 1 d arrays that contain cyclical information (a bit like a sine wave).  One that contains information about the position in degrees and another that contains the couple.  I would like to calculate the value of maximum torque whenever the station is within a certain range (for example, 30 to 80 degrees).  The beaches are repeated - that is why it is cyclical.   I use the function "in the range", a structure of the case and the shift records to build a new table with the values that are included in the beach I said - that was easy part (see attached VI).  I'm struggling with a way to calculate a maximum value for each sub-table formed when the values are 'in range '.   Your help is very appreciated.

    vt92 solution worked!  I agree that there should be a simpler solution, but your to works fine.  Thank you very much.

    This can help you

    Assuming you data in a table named 'Data' and the information is summarised in another table (right) named "Summary".

    Select cell B1 in the summary table and then type (or copy and paste from here):

    = SUMIF(Data::C,a1,Data::B) ÷COUNTIF (Data::C, a1)

    shortcut for this is:

    B1 = SUMIF(Data::C,a1,Data::B) ÷COUNTIF (Data::C, a1)

    Select cell B1, copy

    Select column B, paste

  • How to calculate the difference between two times by the NUMBERS

    I'm so bothered by the fact that I can't understand that.

    I know it's probably one of the most basic operations, but for the life of me I can't understand it. The cells B2 and C2 are formatted for a 24-hour clock. But if I tell the system to just subtract the two, I get "0,118. Everything I find on the forum search goes beyond what I need. Can someone help me?

    Thank you

    Hi sapirs,

    Departure and arrival of the cells are in Date and time with Date format: no and time: 24-hour clock.

    Formula in D2 (fill down)

    = C2−B2

    The results become a duration format, but under automatic (numbers automatically worth this format)

    If you wish, you can change the cells of lasting results.

    What Data Format have your result cells?

  • How to calculate the execution time of a SCTL in FPGA VI?

    Hello

    Can someone guide me that how to calculate the execution time of a SCTL for an iteration in the FPGA VI?

    Thank you and best regards,

    Rashid

    Hello r,.

    A SCTL will always run in a beat the clock it has been linked to.  So, if you use a 40 MHz clock, this loop will run in 25 ns.  If the code cannot complete in that, or if it requires two graduations of the watch to do the calculation, your code does not compile, then you have the guarantee that this will always be how long it takes this piece of code to run.

  • How to calculate the equation of dataset using 'Fitting VI' (non-linear or polynomial fit)?

    I have the datasheet of a NTC (thermistor negative Coefficient) and I want to calculate the most approximate equation

    that describes its behavior. The table has values of temperature and resistance. If the resistance of the NTC varies according to the temperature it detects. I tried the following:

    -Excel: polynomial adjustment

    -Maple: polynomial adjustment

    -LabVIEW: Polynomial Fit.vi

    I've been doing equations with a not very good approximate parameteres. I suspect that this method 'Polynomial FIT' it is not the best method for this type of data/equation (being a non-linear equation).

    So is - that someone has used the non-linear Fit.vi matching the behavior of a dataset object? If so, can you explain how this VI... I would really appreciate it.

    Thanks in advance and I will wait for your reply.


  • How to calculate the signal / noise from the graph?

    In my current project, I read a periphera voltage signal. the signal lead noise even after filtering.  So, to identify the necessary data, I averaged the signal.

    I have attached the file with an image of graphics. In this graph, the recorded data are drawn black and medium online graph is plotted in red. Now, I have to calculate the ratio of signal to noise to specify with these peak values. How to do?

    As the signal passes through zero, be careful in the way you set the signal / noise.  For sinusoidal signals, that ratio is defined as the RMS value of the noise (the signal with the desired sinusoidal signal deleted) divided by the effective value of sinusoidal component.

    First of all I would like to subtract the average value of the raw signal.  The difference is the noise.  You can set the signal / noise.  A RMS calculation might work.  If you have a mathematical model for the desired signal, a fitting for this model can be useful too.

  • Calculate the peak-to-Peak Amplitude

    I wonder if it is possible to calculate the amplitude peak to peak of a sine wave. I have a waveform of a proximeter for a period of ten seconds and would like to calculate the amplitude peak to peak for each cycle.

    The DIAdem analysis window has a peak/Valley feature that will allow you to find the peaks and valleys of a signal.   Depending on the exact service you use, you can either keep those results as a 'results chain' or a new property of the wave.  Whatever it is, once you have found the peaks and valleys, you can add the pic to the absolute value of the value to find the full peak-to-peak amplitude.

    If you need to do this in an automated way, you can write a script fast enough to call these functions programmatically.
