Hi, I'm having trouble finding the value of a variable using symbolic operations. Let me explain:I want to find the variable (theta) of a symbolic function within a range of valuesI'm using Mathcad 11

I'm using MathCAD 9.0.0.0. I get this error on my last equation... 

I'm using MathCAD 9.0.0.0. For whatever reason, MathCAD is having a problem with variable units of my final equation in my attached file. 

Hi, This does not help. The download link takes me to the email request form. There is no option to choose the version. I need to install version 10. I have version 11 but I need to share files with  a client that is using version 10.

I'm using MathCAD 9.0.0.0. In my program I have the formula...I have every variable set in my program accept h2 that's in the equation twice. Is there a function to solve for h2? Otherwise, I guess I can rewrite the equation to solve for h2? Thanks,Brent

I attempted to use Mathcad Prime 11 to retrieve a Mathcad Prime 7.00 file I created but I could not. The file extensions appear to differ.  How can I retrieve this file into Version 11 without having to recreate it?  Thanks!

We recorded Andrew McGough (Mathcad Product Management Director)'s one-hour demo and Q&A session about PTC Mathcad Prime 12, set to release in April 2026. Andy discusses: A summary of Mathcad Prime’s newest features, including the recent Mathcad Prime 11.0.1.0 maintenance release The current Mathcad Prime roadmap Demos of some of Mathcad Prime 12's upcoming features I also posed over a dozen questions to him asked by Mathcad users, including some from PTC Community!

Hello, I want to create the  origin  function within a dropdown list (combo box) for an array index operation. Is this possible? I'm using Mathcad version 11

I am using Mathcad Prime Release 9.0 and Datecode9.0.0.0Issue occurs using Mathcad Prime v9.0 and printing a file to PDF using either Adobe PDF or Bluebeam PDF.When PDF-ing Mathcad Prime files that use "Areas," which are collapsible containers for portions of the file, the contents of the Area are printed as raster images instead of text. This is problematic for several reasons:1. Rasterized text is not word-searchable or selectable2. File size balloons considerably compared to text3. The PDF takes much longer to print since the text must be converted to raster by the PDF distiller.Is there a workaround or has this issue been addressed in newer releases of Mathcad Prime?

The values of a symmetric function f(x, y) are calculated and entered into a table using the matrix(m, n, f) function. However, taking into account the function's symmetry effectively doubles the computational effort. How can I eliminate this double computational effort while taking the function's symmetry into account?

I tried to download the Mathcad Express version but I dont recieve the email with the installation file. I've checked junk mail and filters and there is nothing there.Thanks,Peter

Hi folks, My problem is a simple one - calculate the vertical overburden stress in a soil mass.  The simplified equation is just [ unit weight of soil ] * [ depth ].  However, in a layered system with a different unit weight for each layer, the calculation is best formed as the sum of the vertical stress increments. To me that looks like a stepwise function constructed as a series of IF-ELSEIF-ELSE statements as shown in my example below.  It works but there is surely a more clever way. Lets say the bottom of layer 1 is z1 and the stress is p1, and the stress at some mid-depth in layer 2, say z2, is delta_p2, such that the stress at the point in question is p(z2) = p1 + delta_p2.  What is the most efficient way of structing that calculation as a function depth (z) so that it can be scaled to any number of layers.  My best idea so far is an "If" function to evaluate the stress at the bottom of each layer plus the portion of the n-th layer at the t

I have a matrix and would like to obtain the product of rowi+1/rowi How can I do it?

I went from one broken PC to another, and I can't get a license on the new PC. I tried the website to obtain a license, and I got "you have reached the maximum number of licenses". I can't open a ticket because I don't have permission for an ID. What an absolute runaround. I will never recommend this product to my employer. Please fix this or give me my money back. I have wasted the last 3 hours.Charliecroy1@UAgrantham.eduMathcad Prime 11 Student EditionOne-time LicenseelectronicYour product key:

I am using Mathcad Prime Release 10.0 and Datecode10.0.1.0I am trying to draw a contour plot for a publication paper. I drew the contour plot but when I export the plot to the paper after reduction to fit a double columns format paper the fonts of the contour plot axes and the legend font are too small and not readable. I tried many things and could not find a way to control the font size of the plot and legend. Need guide what to do.Here are the errors that I facedNo error message.

I was playing around with sorting and decided (yet again) that I was frustrated by some of the restrictions.  One thing led to another, and before I knew it, I was hip deep in ways to "improve" the lookup functions.    While contemplating Mathcad Zen Principles 3, 6, 7, 16, and 17, I wondered whether "unique" would be a worthwhile addition to the match/lookup modifiers.     Then my mind went blank when faced with how to handle NaNs.  In principle,  IEEE 754 NaNs are distinct.  And they would be if a standard Mathcad user had any way to distinguish between them, but they're harder to tell apart than Zathras and Zathras.  To the Mathcadder in the street, they might as well be indistinguishable, for all the good their distinctiveness does.   So, I've written two versions of unique to cater for both cases.   The question is which one would a user expect to be the default (and hence all lowercase) version?   I'v

I purchased the software - now how to i get the down load?So far the purchase experience is not good. Too complicated.

I can't seem to create a scatter plot using a Chart Component.   Is there a way to do this?   

Is there a way to re-read Excel Data that has been imported into PTC Mathcad using READEXCEL? At the moment the only way I know how to re-read the Excel data is to delete the following and re-import:  

Hi there Why I'm having the wrong answer when calculating Re using (In) When Mathcad calculates it I get Re= 1.65 , however in my calculator I got Re=0.67 Thanks 

How is the person in this video creating a vector from the matrix?    What key sequence is used to achieve this?  https://youtu.be/Diq4hwvpPlw?si=SugsH3nFn_1xbJfR&t=34 

In Mathcad Prime how  do I specify that I want to establish a matrix that has 2 columns and 91 rows?

The curve should be smooth.
