Management has asked me some questions about MathCAD 15 that our users are refusing to upgrade to MathCAD Prime 9. We have licenses for both programs. Are there any security issues with using MathCAD 15 and the files it generates? We are working in the nuclear industry so a lot of the calculations and data used are classified and we want to be sure that nothing in MathCAD will allow that data to be inadvertently compromised. Does someone know when the End of Support date was for MathCAD 15? We can maybe use this as leverage to force the users to adapt to MathCAD Prime 9.  

An image imported into Mathcad when scaled does not show properly. It does not matter even if the image is having high resolution. This problem has been persistent since many versions of Mathcad Prime. Please fix the issue.

I want to write in my new book like this.What do you say about it?"Mathcad has become a kind of stepdaughter at PTC. Previously, this program had a mother - MathSoft, which in 2006 sold itself and its daughter for almost $ 100 ml to PTC. Now the Mathcad program is not a separate mathematical program like Maple, Mathematica or SMath, but works as a servant of Creo CAD and gradually, alas, dies. ORIGIN Программа Mathcad стала некой падчерицей на фирме PTC. Раньше у этой программы была родная мама – фирма MathSoft, которая в 2006 году продала себя и свою дочку за почти 100 мл долларов фирме PTC. Теперь программа Mathcad не является обособленной математической программой как Maple, Mathematica или SMath, а работает служанкой у САПР Creo и постепенно, увы, хиреет.  

Is there a way to maintain hyperlinks in the pdf versions of Mathcad documents?  

Hello,           We see that in the case of the function Test1 Arg(Test1) cuts -180deg line, as a result, we can have values ​​for:   But in the case of the function Test2 Arg(Test2) does not cut -180deg line, and this means that: or or   But I get the red color:   The idea is that I don't want to see this red color (although I know from where this no answer/red color comes -> because the graph does not cut -180deg line), but instead, I want to receive as answer one of the 3 options listed above. Is this possible?   Mathcad Prime 8 file attached.   Thank you.  

Why we have 3 functions lspline, pspline and cspline? Can we have only one spline?        

Hello,I have the following problem. If I e.g. Define 2 variables (b:=5 & h:=2) and then assign them to a new variable (W:= b*h) and then press =, then the following is displayed: W:= b*h=10However, I would also like to see the formula written out and then the result: W:=b*h=5*2=10 When I do that with symbolic evaluation and keywords, it doesn't look pretty.So is there a way to have formulas written out like above before I see the result?This way you can understand the calculation better. Thanks very much.   Translated by Andra Chirila using Google Translate on April 21st, 2021----------------------------------------------------------------------------------------------- Hallo,ich habe folgendes Problem.

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.

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

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?
