Mathcad

Somehow I came to this error making this problem to work, could anyone help me out fix this please.

Please tell me how can i solve it?

Can anybody tell me why "atan" doesn't work?  Or what mistake I made ?

Hi, I'm using PTC Mathcad Express Prime 3.1 for my UNI work.Unfortunately, I hate using Tahoma as my default text font. Is there a way to permanently change the default text and math fonts to something like Cambria Math?

Hello all, I am currently working on a project involving calculations for a Helmholtz resonator and I got stuck with not achieving the proper units in the final results. below are the starting formula and a snap shot from the MathCad project. As you can see, numerically it checks out. The numbers are right, this is what it is supposed to show.However... L units should be mm, not m/s. If I run out individual calculus, multiplying or dividing.. somehow it looses up the degree unit. it only shows 1/s instead of deg/s. Also took into considerations that it might be thinking in radians therefore I added that 180/pi.Also, the plot seems to be a bit off also. Why is the n coordinate going from 1000 to 1900 to 2800...etc instead of 1000, 2000, 3000 how I defined it?However, for the purpose of calculus and further use of those resulting values, I need my L to be in mm. Any ideas on how to fix this?What am I doing wrong?Thank you for your time and help!Cheers.Dan.

Hello everyone. I have a problem with a difference method, shown here below. (The results are different from those of the text). Some of you could kindly say me  if I'm wrong or the text is wrong? thanks a lot.Yours sincerely F. M.

Hey guys,i modified my iterative calculation and it is better to work with that functions and variables.Having now the problem, that the calculation for the second row is not correct. It should be an independend calculation for every loadcase with a different maxiter.And the second example is not working.Can anyone see the failure?THx guys

could you write script float to int

how can i clear matrix symbol with function or commands?like this.

  Hello, Everyone.  solve, W, X, Y, Z ?  Thanks in advance for your time and help.     Regards.

A simplified example probably illustrates my question best:I would like to set multiple variables based on the value of A in my example above.Thanks,Kevin

Can you show me please, when we must use also if not else if. Must not can!

See please MySort     (view in My Videos)

Hi All,I am not sure why the value of Sin (Theta) is not coming out correct in Prime 2.0 (see attached). The calculator value is 0.342. Any advice?Regards,LS

Hey guys,i would need a recursivic calculation with a break condition. I made it so far but now i would need an extention to this calculation.I added a mathcad file in which i described my problem. I hope that someone can help me 😃This is only an example but is describing my problem very goodBest thx!

Is it possible to generate a radio button group with the line items input as a vector?  This would be similar to a list box with one input but with radio buttons for selection.

I created a very simple (basic arithmetic), but long Mathcad file in Prime 3.1 express while away from my home PC.I have a fully licensed Prime 3.0 that I would like to use this file on. Am I out of luck?  Do I need to re-enter this data again in Mathcad Prime 3.0?  Is there any way to convert this file?

To all,I have created a contour plot and trying to control the scale and/or the colour scheme.Under the advanced properties I can see the option 'choose colormap'Q1: with the (default) rainbow map, is red the high value or low value (on the z axis)? look high it's the high valueQ2: I believe (from the doc) one can allocate a colour map ( SaveColormap and LoadColormap functions)Can this be used to create one own scale so that[0-0.1] = a colour]0.1-0.2] = another colour...]0.9-1] = reda 10 band colour mapThanksRegards

I've been working on a problem to determine the formulas for two sinusoidal fibers that are tangent to each other, as shown in the attached picture.  I've already pursued this problem with the GRG Solver built into Microsoft Excel and determined that there are multiple solutions, but I wanted to transition to Mathcad.  After entering the governing parameters and constraints I found that the solver functions if my guess is the same as one of my solutions, but if I change a guess (specifically for A1 or D1 in the file) it will not solve.I don't know if I'm doing something wrong with Mathcad or my constraint equations, or if I'm just experiencing limitations of the solver.I attached my Mathcad file with the most trivial solution entered, as determined by hand.  Slightly changing A1 from 1 to 1.1 causes the solver to fail.Can anyone provide any insight on this?  Thanks in advance.

I was using Mathcad prime 3.1 to symbolically solve a pretty simple equation and I get imaginary numbers.  While I was easily able to just do it by hand, I'm curious as to why it did what it did and how to stop it, if possible. The solutions I've found posted here and elsewhere don't seem to help (i.e. using various assume commands)File attached.Thanks,

Please!

Hey, im encountering an failure here:I want to use for every row another Dp as shown here:Thx ! 😃
