Mathcad

i want to download math cad 11 for students. I already have the version 10. How can i update my math cad? thank you

Dear all, I'm exploring the functions:numerdenomAnd I've encountered the "oddities" in the joined MathCAD file (see what highlighted in pale yellow and the text; in pale blue some reference results for information) To be honest I suspect multiple bugs... If I'm wrong (i.e. we're not dealing with bugs...) , can someone explain me the logic under the quoted functions behavior, because I really cannot understand... Many thanks in advance & Best Regards 

Hi Folks, I have a system of three coupled ODEs that I'm trying to solve in Prime 10.  I seem to have a  syntax error, but the help files are so terse, I can find an example to follow.  I'm sure I'm making a basic mistake, but I can't figure it out from the documentation. I'd be most obliged if someone could point me in the right direction. The attached file actually has two different solution attempts in it.  The first is a state space solution with rkfixed.  I followed a short example from the documentation, but it doesn't work.  The second is the uses odesolve in a solve block.  I'd be happy if I could get either one to work, but the solve block version seems like it takes better advantage of Prime's features. Edit:  I figured out the problem with the odesolve solution.  I defined three of the initial conditions incorrectly.  I wrote x1'(t)=0  rather than x1'(0)=0.  That just leaves the state space

Hi,I have a load of legacy MCD files that I wanted to convert to the new format to use. In the trial version I don't appear to have access to the full functionality of Mathcad Prime.To help me evaluate the software is there anyway I can use the XMCD, MCD converter tab to automate this? Otherwise I'm not really sure how I can use the trial to evaluate the software without the original files?Any help you could give would be apricated.Regards,Steve Fay

Hello @MN_2245665   With reference to this topic. I dont have mathcad 15. when I try to convert it to Mathcad prime 9, i get an error message: Thanks, Sam

Hello newbie here, (user of Mathcad Prime 10.0)I wanted to ask if anyone can explain how to use normal Iteration in Mathcad. Like, I have different equations and I want to create 5 loops or "intervals" to get my answer. I always used "solve block" for iteration, but now this won't work. I want to create something like this: I tried asking AI but it only gave me nonsense. I never used this type of Iteration on Mathcad before, only on Excel. Thanks for any help. Sorry if I wrote a little bit wobbly, English is not my native language. Best regards,Saro : )

How do I copy paste large data in first column of combo box? Rest columns I am able to copy paste the data but first column how to do that? 

I have three stacked blocks with widths denoted as B1, B2, and B3. Each block is 4 feet high, and the bottom elevation of the lowest block is defined by BotEL.The ground surface is represented by a set of known points with X and Y coordinates describing its sloping geometry.For each block, I need to determine the coordinates of two intersection points with the ground surface. These are labeled a1 and b1 for the first block, a2 and b2 for the second, and so on.The "a" points correspond to the vertical lines at the right edge of each block, where the X-coordinate aligns with the block’s right edge. The corresponding Y-coordinate must be interpolated from the ground profile at that X-location, The "b" points correspond to lines forming an angle θ (theta) with the ground as shown. A Mathcad and an image illustrating the problem are attached.I appreciate any help!

Buen dia comunidad, tengo un problema en la iteracion para encontrar un valor (Xcal) donde la condicion es que el valor calculado menos el dato del valor inicial sea cero (Xo = Xcal) o el error sea minimo. Por favor si alguien me pueda ayudar se lo agradeceria. Gracias por la atencion prestada. La version de Mathcad Prime 9.0.0  

Hello, I have solved some problems and formulas in artificial intelligence: Deepseek and ChatGPT then and converted them to MATHCAD format. There are no errors, they are well written, but Mathcad does not recognize formulas or numbers, it pastes them as text... Is there any way to solve this? Is it possible to use a programming language to use the Gauss Seidel and Newton Raphson methods directly in Mathcad? I have the codes in Python but I want Mathcad to generate the .mcdx document for me...

Hello everyone,eff.K shown in picture is radius of curvature along beam length and X is the array for sectional points.I have to double integrate eff.K to get deflection. How can i do it in Mathcad? Attached Mathcad 10 sheet.  

I would like to write a program to create a nested array. I have a column vector containing angle values. I want to iterate through this vector and create an array of arrays with each element being [cos(angle) sin(angle)]. I am sure this is not difficult, but the syntax is not clear to me at present. I think I have been writing python programs for too long.Thanks in advance for any help

I am trying to reinstall MATHCAD 15 (JA150006E3006-Q3PF-8VYW)on a new WINDOWS 11 computer. The installation fails by telling me that MSXML 4.0 SP2 is required. The link provided is dead and Microsoft tells me that MSXML 4.0 SP2 is no longer available.What should I do?Best regards,Rich

Hello,Please see attached file. How can i get a constant value for (EI) to be multiplied by the results of the curvature y"(x)? Thanks,Sam

Nie dostałem licencji dla edukcji 30 dniwoej i przy wyborze instalacji programu w okienku licencja nie mogę przejść dalszej konfiguracji. Proszę o przeslanie licencji lub informacje jak mogę zainstalować program w inny sposób.

I acquired license for 30 days trial on wrong mechine. how can I swap it to my machine? It is assigned to my stationary computer back home and I will be away for long time now and the license will vanish before i come back. I need it on my laptop for university.

Make equivarent sine waveform that has maximum value = 1, average value = pi/2 and RMS = 1/sqrt(2). Below waveform has RMS=1/sqrt(2) but Ea=2/3 not pi/2. ,    Hard probrem. If you can make it, find the Fourier series of the waveform. Calculate the Ea and RMS values for 10, 100 and 1000 harmonics include. Symbolic evaluation by using below programming may causing a trouble.    

I use MathCad Prime. I have N/mm^2 *m*m. The result should be kN but it just doesn't work. I tried kN/m^2 for the f thing, but still doedn't work.

I have the product key but need a license. When I put in my basic account info to get a license, I received an error.I can't proceed further.Please assist meThanks,Steve

I checked other posts about this issue, and I couldn't find one similar to what I am doing hereI am wondering if that is because of the sin function or whatmathcad 9.0.0 file is also attached 

I am trying to assign the result of the symbolic solution of P to P so that I don't have to copy the result and assign it to P manually. See below and the attached mathcad file:is possible to write this so that the result of P doesn't have to be copied?I want to change this because if I change the formulas above, I dont have to re-copy the results

Found what looks to me like a bug. The error message is not very helpful and rather an indication that it is actually an unintentional bug.   In Mathcad the convenient prime operator is not available and so we would have to use Can't check if this way would work in Prime as I am limited to Express and that kind of 'programming' is a premium feature not available in Express. In Prime we get the very same error when using a scalar argument and vectorize   Any comments on this?   Prime 4 worksheet attached    

Hello,How do I set positive y-axis  in the downward direction in prime? Regards,Sam

Hello users of Mathcad : ), user of Mathcad Prime 10.0Here is a picture of my problem. I am trying for days to solve it, I just don't understand why it won't work. I need it for a homework.So, I’m working with a rectangular channel where the flow area is A = b × hn. The problem is that I don’t know either b or hn, so to make things simpler, I just assumed the cross-section is square – meaning b = hn. That way, I only have one variable to figure out.I then rewrote the whole discharge formula so that everything (A, U, etc.) depends only on hn. All the other values like the slope and the Strickler coefficient are given.Once I find the hn that gives me the correct flow rate Q, I can always scale it afterwards, like double hn to get b and turn it back into a rectangle if needed. The most important thing is that the flow stays the same.So theoretically, this should work fine, but Mathcad won’t solve it, and I’m trying to figure out what’s going wrong.Thanks for any help.
