Mathcad

I try to convert mathcad 15 Taylor serie to PTC mathcad 9.0.It seems that mathcad 15 could treat Taylor series with several variables but not PTC mathcad 9.0.After PTC conversions, PTCmathacd 9.0 give the following error : more than one independant variableCould you help me to solve this problem ? Thanks

I have a default set of units that are included in my document template. They are there because I use them regularly.  Having a bit of fun, I have attached a sheet with these and about 50 more.  Who doesn't compare area to Rhode Island or volume to a cord of firewood? Feel free to add more.Bob

Following up on thr thread https://community.ptc.com/t5/Mathcad/LeastSquaresFit-usage-for-Foster-Model-parameters/td-p/100070  Why does genfit blow up when provided with the actual Foster Model thermal fitting function and guess values used within that model when fitting to @VD_12953418 digitized plot data?  I would have guessed that the genfit result would have been close to the plot of the model or to the example of digitized data.

Good day, I am a newly hired teacher at the HTL Rankweil. From there I got a user license for MathCad. I may have made two mistakes when activating the license. I had downloaded version 10.0.1.0. But my colleagues all use version 10.0.0.0. The license I was using may only be valid for 10.0.0.0 and not 10.0.1.0. That's why it stopped working the next day.   Or it was because I used my private email address when registering for the account and not the one that belongs to my school.   Today I wanted to activate version 10.0.0.0 with my school email address. Unfortunately it was not possible to open an account. The system reports back that there is already an account.   That's why I would like to ask you to delete the account based on the private email address.   Thank you Torsten Soetbeer     Translated by the Community Moderation using Google Translate.    Guten Tag,ich bin neu eingestellter Lehrer an der HTL Rankweil.

My Mathcad application doesn't start, i tried to reinstall it but with no succes. It only shows that the application is in the taskbar, when i press on it a small window above the taskbar comes up and it is black. I urgently need your help for a project that i am working on for university. Thank you!

I have to use Mathcad prime for my engineering course and since it I cannot purchase it right now I have been using the 30 day trial. So once I started the 30 days I thought it would be fine for 30 days, but for whatever reason the trial period disappears after a couple days or a couple hours, putting me back in mathcad express. My work-around for a couple days was to reacquire the license through the licensing wizard. None of my friends have had this issue, and I have now 'run out of free trials' even though I would be halfway through my actual 30 day free trial.

So, I've been able to work through all the values so far but seems like I have a problem with the summation notation since the THD of alpha does not converge to a solution:     

hi ptc team,i use PTC Mathcad Prime 9.0.0.0 convert xmcd file to mcdx, but there are so many errors in mcdx file,how to resolve? please help.

I encountered an interesting and maybe concerning problem in how MathCad solves its intergrals between different versions. In the version of MathCad I use (MathCad Prime 9.0.0.0.) the integral I wanted to solve and get an analytical expression to gave one answer. This answer is different from the answer you get on older MathCad versions. I noticed this from some old reports where this integral was solved via MathCad about 20 years ago and they get a different analytical expression. This expression you get from the older versions is also the same you get by solving the integral completely analytically (which you can do via variable substitution). The difference between the answers seem to be very little and the residual could just be some numerical truncation maybe, but as we can see the difference is not completely negligible depending on what you are after. Has anyone encountered something similar to this and know why this is the case? 

I'm trying to find the product code for Mathcad prime. How do I find this?

Is it possible to export out a scalable vector file from Mathcad prime worksheet? If yes how can I do that? 

How do you have the plus sign "+" be a subscript? Every time I try to subscript the plus sign, it just becomes an operator. But I want it to be part of the subscript.

Hello all, I'm trying to do a fit for the transient thermal impedance of a transistor based on a set of points that I extracted from a datasheet. At first, I tried to do a simple polyfit, but it seems that the fit can diverge to very high numbers or even go negative, which may not be acceptable in this case, since the thermal impedance is strictly positive.I tried to do a fit similar to the Foster thermal model, based on R and C couples of values, that is usually used in the thermal models of electronic components. For that, I tried to use the LeastSquaresFit function, but it doesn't converge in my case, script attached below. Could anyone explain the reason for the divergence ? Is it the input data or the way it is used ?In the case I try to separate R and C values to 2 vectors, should the guess vector be the stack of the R and C vectors ? The documentation of the function doesn't explain it in a clear way.Alternatively, in the case of a logarithmic regression, is it po

Hi, I need instaling Mathcad 10 in another computer, please send me download link.Thanks

How do I get Mathcad to get from this:to this:without having to redefine f(x) myself?

Hi,Which software do you recommend for verifying bending moments and shear forces in a beam from Mathcad calculation?I use the beam calculator https://solveredu.com/en/beam-calculator/. It's generally good, but do you have any other recommendations?

Hi All, What is the formula to stack the zcal into a vector and rearrange the vector up to the zcal value. Can anyone please advice?  

Dear All, Found the solution to stack and filter the vector to calculated value. I am looking for a loop or formula which I can calculate area under each section of the vector and then cummulate them.  

Hello, I have been having problems with saving/printing the file to pdf. Some pages come out blank (only header and footer is visible but not the content of the page) in pdf without specific reason. It does not happen in every worksheet, just some.Let me know what I can do with it.

HelloI have two issues:1. The system will not accept my product code so i cannot raise a support case.2. My laptop just got a new motherboard. I cannot get Mathcad to activate and i cant download a new licence as it says i have had too many.Is there another way to raise a support case?Thanks

I used to use Mathcad on other computer. I use free Mathcad version only. Now I have new computer and want to install Mathacad again, but I cannot acquire new licence. Can you help me use the old one? How can I get it again?

I am a student and want to purchase the Mathcad Prime 10 Student version (the one for $63/year), but when I click on the link that says "Order Now", it just brings me to the "Mathcad Express Free Download", which is not what I want. I already have Mathcad Express, and I wish to purchase the student version for $63/year, because I am a student who needs Mathcad Prime. In other words, I have found no way to actually purchase/buy the student version of Mathcad Prime. Is there any fix to this to allow me to buy the student version?

Hi,   What is the symbolic engine used by Mathcad Prime (all versions greater or equal than 7)?   What is the numeric engine used by Mathcad Prime (all versions greater or equal than 7)?

Could not install because it would not accept my password or redo a new password to get a PTC.COM account.   Would not install MATHCAD PRIME 30-DAY TRAIL.   too many hoops and hurdles....
