Mathcad

We have an older perpetual version of Mathcad that we need to move from an old computer to a new one.  I cannot find anywhere in my account profile to change the MAC address so that the new computer will be recognized.  Does anyone know how to do that?

Here, the students and I saw an animation on the site Pendulum - Wikipedia showing the position of the velocity and acceleration vectors of the pendulum.We wanted to reproduce the acceleration animation in Mathcad - see the animation and the file in the attachment.But our animation is different from Wikipedia's animation -  we have a maximum acceleration, and there is a minimum. Where is the error - with us or in Wikipedia?  

Hello everyone, I hope you are all doing great in your daily life. I need a little help in solving the differential equation as I m new to MathCAD prime. I m trying to get the solution stated in pdf in MathCAD prime but I m stuck at differentiating the equation. If anyone can help me out I will be really thankful. I m attaching pdf as well as MathCAD prime 8.00 file for reference. PS: 2.pdf shows the results i want to plot, 1 png is the case i want to solve and 2.png are the boundary conditionsThanks   

Hello,     In the end, the result should not be: ?   The calculation was made in Mathcad Prime 8.

I'm trying to check the flange thickness ratio, b/2t, with b=18 and t=0.75. Therefore b/2t=12. 18/(2*0.75)≤12 returns true, of course, but b/2t≤12 returns false. This does not happen with most other values of b and t. What's going on here and is there any way for me to fix it?  

Hello!Can someone help me with a XMCD file. I needed to be converted into a mcd file and I don't have that option in Mathcad.  @ValeryOchkov      

Is there a way to have the internal links be active after printing to PDF?

A friendly hello to all,again i need help. It's about the recursion u(n+2)=7*u(n+1)-3*u(n)+3 for natural numbers n. How does the calculation and tabulation work in MC15? In derive I managed it successfully. But in MC15 everything is possible, just not the correct result. I just can't get a grip on programming in MC 😞 .The background is the transformation of the formula u(n)=((1/2)*(7+sqrt(37))^n+((1/2)*(7-sqrt(37))^n-1 given in Binet-Art into a recursion and examination of divisibility by 3.Kind regards, Alfred Flasshaar

Is there a way to find max values for two columns, outputted as one column in prime 9?    

I'm writing this as I had to work long on a converted legacy Mathcad document to prime.Since being forced to convert legacy Mathcad documents to Prime I get from colleagues (who're proof reading my calculations) the following questions:What does EXPLICIT mean?Why don't you cut down on the surplus decimals in equations?What happened to the tidy calculation reports I used to submit?All this proves that Mathcad Prime is far from the "...professionally formatted document..." PTC claims to provide.  See results in the screen shot below.   

Hi, look like solving block solves the equation, but lower, it says that the variable is undefined. What am I missing?   

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.  

Hi, Can someone upload a worksheet sample on how to use Tags and internal Links Cheers Terry

Hi Guys, Can someone please simplify the final expression for fixed end moment for a point load at any point on the beam? Please see the attached file. Solution should look like below expressions of Fixed end moment Ma = -Pab^2/L^2Mb = +Pa^2 b/L^2

Hi,can someone please help me?I want to find minimum non-zero value, in col B and its respective values in col A & C. Thanks in advance.  

Mathcad won't allow me to expand the attached expression into a series because of a singularity. Yet the publication shows that it can be done. Any suggestions? Please see the attachment.

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?        

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.
