Trying to plot a simple X Y plot for function below.  I get an error using units but none once units are removed.  I'm missing something basic. Help appreciated.  

Does anyone know what the internal processing limitations of MCP are w/ regards to the max processing speed and the number of cores, etc.? Same question for multithreading turned on and off. My company recently purchased a 16-core, 3.2GHz/5.0GHz 'power computer' and I would like to know how much MCP can take advantage of this machine.Thank you! 

Hello everyone!I can't determine the origin of the 180-degree offset, between the two results, one in the first worksheet and the other in the second one. As for the creation of the graphs, with the interval chosen, it takes a long time (many minutes). A tip to speed up the drawing? (see photo).I enclose two worksheets dedicated to the same problem but with different methods.Thanks to whoever will answer me.

Hi allHas anyone encountered this before? In my Combobox, dimensionless inputs get units. You see the problem below. I'm thankful for any advise how to get rid of the problem 🙂       

Hello,       ????   How can I extend the above x(t,...) signal which is defined from -pi to pi to a periodic one so that I can display more periods of the signal, as it is shown below?     Mathcad Prime 8 file attached.   Thank you.

I was learning to use MathCAD with a trial version. I had a Excel sheet in my Mathcad file with some calculations. Since my trial license has expired, now I am unable to open the excel sheet. Could you please extend my trail version to recover my excel sheet or is there other ways to extract this excel?

Hi, I'm having an issue where the vectors in the image below con't calculate into a result. The second image is the one where the results should be. I'm using Mathcad 20, so it's pretty old, and the original author of the workbook isn't around anymore. I can't see anything glaring and there was definitely a result from the workbook at some point. If anyyone can help it'd be greatly appreciated! Thanks, Tom        

Hello,       Do I need to define the dirac delta (unit impulse) function separately to be able to use (plot) it?   Mathcad Prime 8 file attached.    

please I don't know how to overcome this error   

Can't access MathCAD with my school account for some reason. It works for other students

Hello,   Input: where  is the step function:         Rewriting the above result:   And calculating fourier transform by definition for the above input, results:  (which is the correct answer)     So, where is the mistake? The 2 above results should not have been equal?   Mathcad Prime 8 file attached.    

Hi Mathcaders,I am alittle bit confused on how to use lookup on mathcad prime 8. problem statement:I have a table of containing Steel section name and elastic section modulus as given below: In my work, I have to calculate an elastic section modulus and match with values in the table and choose the profile with the nearest upper value.  My trials:1. I used the following expression: It only compares the first digit. The answer is always AZ12 until I increasesd the calculated value to more than 2000.  2. I used the following expression ( I got it from the internet)The answer is the same as before.  Any help please?   

When I go to install the trial version I get the following error: Cannot start installer Check your network connection And I have already checked all the connection and I have changed the network but it is still the same, how could I solve it --------------------------------------------------------------------- Translated the below text from Spanish to English using google translate on 10-April-2023 at 9:31am IST, by vnamboodheri Subject:  Error de instalación versión gratuita Body: Al ir a instalar la versión de prueba me aparece el siguiente error: No se puede iniciar el instalador Compruebe su conexión de red Y ya he revisado toda la conexión y he cambiado de red pero sigue igual, como podría solucionarlo ---------------------------------------------------------------------        

I need to increase solve speed for a large worksheet.  I click the multithreading button.  First, it is not clear how to detoggle the pick.  Second, the CPU time went up.  Under what conditions does this option work.  Or is this just a vaporware feature of P8? thank you

I have generated three plots for different z or distance now i would like to compare the width of axial maximum and the width of central maximum is the value r from 0 to the point where the cure achieves zero.  I want to normalies and assume the value achive r=0 and i want to divide all values of I of I(r=0) how its possible to do this in mathcad please help!   

We are trying to convert MathCAD programs to MathCAD Prime 9. After the conversion the resultant graphics are not display the grid axis that the users were getting in MathCAD 15. Is this a display setting or an issue with MathCAD prime?  

I am trying to install a free trial of mathcad to run a calculation that was provided to me. when I open the "mathcad prime installation assistant" I get to the third step - application selection - and there is nothing in the window to chose from.

Hello,     Mathcad Prime 8 file attached.    

We are trying to get our MathCAD users to use MathCAD Prime 8 instead of MathCAD 15. When they go to open a 15 file in Prime 8, it is asking for a 15 license. We have removed all 15 licenses to force them to upgrade. Why does MathCAD Prime 8 require a MathCAd 15 license to open and convert a file? This will be a major draw back in getting the users to upgrade.  

Several cities have installed arrays of microphones and use the time delay of the sound of a gunshot to triangulate the location where the shot was fired.  After several months of stumbling around I managed to get Prime Express to do this calculation.  (In my previous life a solve block would have made the job simpler.)   So let me crow a bit!  Prime 4 Express attached.

Hello.Our company had a PC that acted as a license host. Recently this PC has crashed.  We raised a virtual server in order to transfer the existing licenses to it, but the error occurs: "Upgradable products not available or already used on provided Product Code". And it is not possible to untie licenses through your personal account, because "Complience Hold".  Tell me, please, are there any other options to restore licenses?We have MathCad Prime 3.1

Hi,I'm trying to understand how the IFFT works.The most difficult thing to be understood by me is the reason why, having 2049 complex samples (p0) I get as a result (4096) real numbers.The complex samples are not generated by me, are the result of an algorithm written by others.So I try to understand if there is something special in those samples.I tried to compare the result with what I get with Wolfram Mathematica (sorry about that):InverseFourier[p0, FourierParameters -> {1, -1}];and I get (2049) complex numbers. To get something similar in shape I need to take the real part of those numbers.Beside that the result of the IFFT is 2048 (magic number!) larger than the result of the InverseFourier.Can anyone explain to me the reason of those "mysteries"?Thanks 

Hi, I would like your help to convert MathCAD 15 file to 7 Prime (see attached). The conversion dialog shows conversion failure. Thanks, -Peter
