Mathcad

Hello, I'm not that experience with Mathcad, I do with excel, there the index match function is quite handy, something similar I would like to use in MathI would like a lookup function in a matrix, to return as output from the matrix, not the value, but the name: I'm not sure if it's even possible, have searched throughout the internet without results.. Thanks for helping!

I checked this section for a similar question and could not locate one. It's simple one I'm guessing but I just cant figure it out. Two equations: 3x^2 + 4x -7 and 5x^2-7x+3 (or whatever one variable equation). How can I add them in mathcad so I get the answer 8x^2 -3x-4 ? Thanks. Mr Noob....

I cannot find where to download the software to install. Do I download the trial version for Mathcad Prime 8, and then, select my licensing dat file for the student version?

Hello everyone!Why does the symbolic processor give me different results in calculating the sum of the infinite series shown in the photo? Does Prime produce the same results?

Hi guys,   I have a question.. I modelled a 4th oder ODE in MathCad which works smoothly.. But when I tried to upgrade the script into (a system of ODE’s) 3 or 4 ODE’s, I couldn’t get it well working.   Note that I checked the boundary/matching conditions and they are correct. So something else could be wrong.   I’ve included the file in the mail.     Would you like to help me here?   Thanks in advance!  

Hello all, I believe I am suffering from a similar problem to a previous post; Solved: Mathcad Prime worksheet Running Slow Compared to M... - PTC Community I have a legacy calculation converted from Mathcad 15 that is mathematically very simple but approximately 170 pages long and as you will see from the attached is butchering my cpu.  The aforementioned Prime calculation is consequently running painfully laggy and occasionally crashing.   Does anyone have any recommendations on a sensible procedure for processing such conversions that goes beyond the standard PTC Mathcad Migration guide? For example, is it advantageous to break the calculation up into areas and disable them etc... @VladimirN , @terryhendicott 

Making some calculations with MathCAD I got an error such as: Unknown error: A call target threw an exception.Is there some stack trace which I could investigate to comprehend the situation? Thanks in advance. 

I converted a part of file from my Mathcad 15 worksheet and getting the error due to this i am unable to proceed with calculations Can it be converted somehow?

The LIcense .dat file does not seem to be working when installing on a new computer.

Can anyone recommend a good introductory text book for mathcad (I've got Mathcad15). I need something that covers the math operations, with plenty of fully explained examples (with keystrokes etc)? I use Mathcad as a math person (not an engineer). Many thanks. Peter Kirby.

We are currently using standalone Matchcad 14 and 15.We are encountering issue with the software. Mathcad is blank and showing break lines. Please advise how to rectify and also how to update the software.

Has anyone tried this... really important for school that's about to start :E I would like to keep using open source alternatives but I must make sure I can still learn like the rest at my schyool. Thank you!

Hello!I wonder if there is any way of plotting parametric curves where the parameter can't be  expressed in terms of variables ("x" and "y"). Example 1: Parametric curve x=t^3 - 4t,  y=t^2 can be plotted by using this equation x=sqrt(y)*(y-4). File attached. Example 2: Parmetric curve x=t^2 * sin(t), y=t^2 * cos(t) - "t" can't be expressed easily in terms of "x" and "y".(or is it correct to write t=asin(x) * (asin(x))^2 ?) Best,Sergey

I have been trying to create a simple while loop and just can't figure out the error Mathcad keeps prompting. Can someone suggest what the issue is here?

I used to have this problem when I had regular sheet. However, now, I'm using API and input everything using API, but my output isn't refreshing. I have to open, refresh and open again by hand. Anyone faced this issue before?
