When doing symbolic math, sometimes the result has exponents of exponents, for instance (x^2)^(3/2) A simpler form for this expression would be x^3, but even using "simplify,max" does not change the form of the result. "combine" and "expand" don't help either. Is there any way to get Matchcad to simplify this expression?
Hello Everybody, I have a query with interpolation: We have 2 tables of data X1 and X3 with 4 items for each table (or matrix, vector)X1 at value of arguments 10 X3 at value of arguments 20 I want to interpolate at 12 of arguments? Can anyone help me?
Hello, I'm Mathcad newbie. I am unable to solve to get the results of figure 2, in mathcad. can solve ...... thanking you.
"Browsing", among the questions asked to the community of PTC Mathcad, I see that there are some of the year 2000 .... but I also see that my recent publications (a few years ago) on analog equivalent-digital filters (Electrical Engineering), are unavailable .......why?
There is: Lemniscate of Bernoulli Lemniscate of Booth Lemniscate of Gerono Victory Lemniscate (now is 8-9 May) - see the animation bellow Questions: Do you know one more Lemniscates? Can you create more intelligent method as in attach?
Hi All, I have written an iterative formula on pg 10 of the attached but cannot work out why it doesn't work. Could someone please give it a second look? Thank you in advance for your time and help. Cheers, Dan
Hello. I have the following function: There are two intervals above 0 in which the value of the function is bigger than 0.2. How can I get those intervals? Thanks!
Hello, I'm Mathcad newbie and I can't get it to do anything useful... Given the following set of equations: I provide values for f and Cs: Now I'd like to 1/ Provide Rp value and get Rs value OR 2/ Provide Rs value and get Rp value. How can it be done without duplicating the equations ?
... I see that, from a bit of time, .... old stuff goes back to the surface ... ..... while the Mathcad community gives me the impression that, is sinking ...... in the hands of a madman ....
Say I have an equation of: Cc = 78.4232/(acosh(1+5.05/Cc)+acosh(1+12.85/Cc) I know how to calculate this through a calculator but not through any means of mathcad tricks. Please help! I'm new to mathcad. (P.S. I've went to many forums and when people also ask about these kind of questions the answers are ALWAYS telling them to simplify the equation by hand (not through mathcad) and then use mathcad to solve. e.g. x = sqrt(12.85/5.05)*(78.4232-x)^2
In this chapter, we will explore how Mathcad can be used to help you manipulate and solve equations. You will learn that Mathcad can solve an equation for any variable, substitute an expression into an equation, and even solve multiple equations for several variables simultaneously. In addition, we will give advice on how these features can help you solve the tough, multiple-step problems in some of your math and science classes.
There is in a Mathcad 15 file with the problem of a circle an a point - a finding a distance between a circle an a point. Help me please to create same function for an ellipse!
hi all, i'm running a recent install of Prime 4.0 on Win 10. i'm doing a bit of matrix math. Using eignenval is fine but eigenvecs is problematic. It might solve once or twice but when i go back up to change a parameter value, the sheet tries to recalculate eigenvecs, stalls for ~10 seconds, then shuts itself off! sheet is attached. cheers, blake
O.K. I have saved this file in compressed folder . I have tried to open it repeatedly and I am told it is not a valid XML file. Why does this occur and how can I correct it
Hallo, ich verwende Mathcad 11 für "Psycho-Mathematik", wobei das Betriebssystem des Gehirns modelliert wird.Zur anschaulichen und möglichst verständlichen Darstellung würde ich in Mathcad 11 die räumliche Funktion einer Kugel in Form eines Netzes benötigen.Am liebsten in Parameter-Darstellung: (A,B,C) im Raum. Die Kugel würde dann mit verschiedenen Radien animiert.Könnte mir jemand eine möglichst einfache Funktion zur Darstellung einer Kugel im Raum beschreiben?Mit herzlichem Dank im voraus, Wolfgang Issel
I am a korean so I can't write well about my questions. But I will try to write.I want to express 'Loop'. Let's we suppose two equations. One is X=Y^2+2Y+3. The last is Y=X^2+3X+5.I can find adequate value by finding convergence between X and Y. But I can't express in MATHCAD. I think I need to use 'While' to express..How can I express it to use 'while'?
My Mathcad 15 refuses to open XMCD files: The error message is "Not a valid XML file".Am running on WIndows XP Pro.Before this happening, MCAD crashed, with a message indicating that it had to close due to internal error. But it wouldn't close, I had to shut it down manually (Task Mgr). Have restarted MCAD and then Rebooted the PC, it is still giving me the Non XML file error?Any advice on that much appreciated. I am in the middle of a big HomeWork that is due Monday and this is a terrible set back. Should have stuck with 2001!Are there any programs that 15 is known not to like to work side by side with?I usually need to have Word, Excel, Adobe reader and the browser (Firefox) open while doing the Mathcad tasks.Thanks for any help on that. Would I need to reload 15? This scares me due to the difficulties I had to get my Student licence going. Thank you.

Hi i have problem, i don't have same result with lookup function on MC15 and Prime 4 On Prime The matrix A is same matrix to MC15 The convert tool doesn't work
hello i am not sure what went wrong here but on the picture bellow the two numbers should be almost the same. can anyone help me what i did wrong
Hello, I have some detailed 2 or 3 page calculations that yield a final stress number. I want to put these detailed calculations at the back of the .mcdx in an Appendix on page 5 or page 6. I would like to keep the end result i.e. the stress on page 1 sort of like this.. S=10ksi (for details please refer to Appendix A on pages 6 thru 😎 I would like S=10ksi value to change if I change something in the Appendix on pages 6 thru 8. Sort of reverse of what happens in a regular .mcdx file where the calculations are before the final value. Is this possible? Any ideas?
Hi All, Why the solver fails if I insert, into the solve block, the constraint highlighted in green ? And how to correct it? What to do to have the polar plot equal to the complex plot below depicted? Thank you very much. Frank
I can't install 3.1 version. What I must to do?
Hi, I want to calculate the center of gravity of all parts above various cross sections (k0, k1 & k2). So in the picture below, I calculate the center of gravity of m1, m2 and m3 at cross section k0. The next row would be to calculate the COG of m2 and m3 at k1 - and so on. I would like to express this with a simple equation. Would appreciate any help.
In the attached worksheet (Mathcad 15) d is apparently undefined. Why is this, it is defined before the solve block as a guess? I assume I am overlooking the obvious
