Mathcad

I am not sure if my syntax is correct but for some reason Mathcad Prime 3.1 will not solve the following simple 2nd order ODE symbolically. The ODE has this form v''(x) + v(x) = 0 which i believe is the same form solved by Euler. This equation is used to calculate the column buckling equation used by structural engineers. it would be disappointing to learn that math done more than 250 years ago still cannot be computed by the latest version of Mathcad. I would find it hard to believe that MuPad symbolic engine dosen't have such functionality? Is there some hidden software switch in Mathcad to enable full symbolic capability? Or maybe someone could show me a workaround. I am just interested to see if Mathcad gets the same result as in the text book. Mathematica certainly gives an unreconisable form of answer, to me at least when done by hand.Thank you in advance Mark

it`s Parabolic cylinder function - Wikipedia, the free encyclopedia I need to input D of order (-0.5). Thanks

Good evening.I cannot open my Mathcad files. The error message above appears. The files cannot be from a newer version of Mathcad as I have always used MathCad Prime 3.0. Any ideas how to solve this problem?

i need to write a function and i have this problem. could someone help me with this ?

Help me to programming the numerical method shown in the attached pdf file

hey could someone help me with this ? i need to putt this function into mathcad prime 3.1 and i have no idea how to do it. help

Hello.The question I have is whether you can convert a string to var, in other words, remove the quotes (") of the variable. Example:                         "Text" -----> TextThanks in advance

Hi everyone,I am using mathcad version 8 to do a symbolic calculations.  I am getting good results until my results that are in series exceeds a certain number of terms.  For example, I am taking a product of two series and integrate them to get the results or Aseries times Bseries = Cseries then Integral of Cseries = Results.  I am getting results when Results series are up to 8 terms.  However when Aseries and Bseries have more series terms, when trying to calculate the Results I am getting the error message saying that "results are too large for the screen" and it does not display results.  Sometimes Mathcad shuts down unexpectedly.   I tried a trick by letting D = Results and defining E = Result series in 6 terms and it displays then E up to 6 terms.  Then to find other terms I tried F = D - E but it failed by displaying error message or shutting down unexpectedly.  Does any one knows a work around this problem or some kind of trick.....

hey, i need to write a function like this. please help

Hello,After a few hours of searching the web to finally get my calculation done. I don't have find a reason why I get the error undefined variable.Can you please help me out with this?Thank you!

I'm plotting an equation using a range variable to sweep x.  I'm also using a range variable to sweep another variable in the equation (3 values).  I expect to get 3 different lines on the plot, which I do.  However, there is some additional solid "fill" in the plot that I don't want.  I just want the 3 lines.  Ideas on how to get rid of the fill?

Hi,I'd like to know: what's the maximum array index in Mathcad Prime 3.1? Someone know about it?I know that Excel 2013, for example, supports a maximum of 1.048.576 rows and 16.384 columns as a limit. And Mathcad Prime 3.1?Thanks so much.

Hi,Is it possible to do with Mathcad of Mathcad Prime?1: shade the area the encompasses the inner 68 % of the normal probability distribution, that is +/- 2 standard deviation from the mean.2: shade the probability (0.212) that a random variable is below 360 with a mean of 400 and standard deviation of 50 pertaining to a normal distribution. If yes, how?Thank you very much!Johny.

Here's a problem that I'd like to solve, using Mathcad, but I don't know where to start because I lack the proper domain knowledge. Is there anyone who can help me on the way?Thanks in advance for any help.

Please help me to program the numerical method shown in the pdf file !!

Hello everyone,What can I do to prevent this?in order to have a result, I had to consider the operators as variables.Thank you for all.F. M.

It is known that for a second-order reversible reactions 8 kinetic mechanisms are possible:1) A1 + A2 <-> P1 + P22) A1 + A2 <-> 2 P3) 2 A <-> P1 + P24) 2 A <-> 2 P5) A1 + A2 <-> P6) 2 A <-> P7) A <-> P1 + P2😎 A <-> 2 PHere, A - reagent B - product. I found a general solution for all the mechanisms that can be represented relatively simple formulaWhere r.o - the initial reaction rate, alpha and beta - parameters that are dependent on the rate constants of the forward and reverse reactions and the initial concentrations of the reactants.For each separate mechanism, these parameters have different values.Accordingly, I want to make changes in the second edition of the material with respect to the second-order reversible reactions.

To all,A really stupid question but one I need to askI have the equation D=S^b where is a non-integer (ie a real). Mathcad does not have a function to return S if D and b are known?ThanksRegardsJXB

Had some problems with calculating the concentration. Couldn't find the way to receive positive solution at the end. How it could be done?
