Mathcad

I installed Mathcad Express (7.0 and 8.0 tested) on reseted windows 10 and it worked correctrly. As soon as I installed NET 7.0 (https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/sdk-7.0.102-windows-x64-installer ) and rebooted the computer - a bug appeared:- create a text field (Ctl+T), enter the text;- enter the formula (Ctrl+Shift+M);- select the text (Ctrl+C);- paste the text - it is inserted without a formula (but if you copy only the formula, then it's copied correctly).Strange things:- The bug remains after NET 7.0 uninstalling. But I tried several times to reset windows 10 and after it bug is disapeared. And bug bring back every time after NET 7.0 installing and computer rebooting.- All others clipboard operations works correctly - only pasting text+formula into text area works incorrectly.Please give me a hint, what is special about this functional realization? Otherwise it is not clear what to write to NET developers in bugreport.   

Prime 8 . No file attached. Trivial inputs. How do I get 3 ?          

Many features previously used in MathCAD 15 are not available in MathCAD Prime. Is it possible to purchase the version of MathCAD 15, and if so, how much does it cost for 1 seat?Sincerely, Sergey Maslov.

Hello, s is a variable.The result should be: It seems that Mathcad Prime 7 does not want to show the result, to calculate...Mathcad Prime thinks, thinks, and thinks again.I gave him such a complex calculation that he can't do even that much?

Weird one this...I get random floating point errors in a quite intense worksheet. If I cut the offending formula and paste it, the error disappears.The worksheet contains too much information to attach it. I just wondered whether anyone had come across this and whether there is a solution. I've also had problems with some plots in the same worksheet as it says the matrix should have real numbers. I have added the Re() function which seems to deal with this problem most of the time. There are no imaginary numbers in my calculations that I am aware of. I'm reproducing calculations that run happily in Excel.  

When acquire license, it is state that could not establish secure channel for SSL/TLS with authority 'apps.ptc.com'.

I recently had to switch to Mathcad Prime when my renewed license would not work on Mathcad 15. But in prime the converter button is greyed out. I have multiple files I still need to access so that I dont have to recreate them. Is there a solution for this. My current will not open 15 at all.   

It would be possible to extend my Mathcad trial student license because I'm didn't get to use the first 30 days due to a personal issue, so, now I hope to get familiar with the software and the advantages that it could bring to my studing process.Thanks!

As per the original post..   Hello. Can you help me to convert this file to MCDX? Thank you very much.

How can I copy paste the table from one to another in Prime with unit?

I would like to take time derivatives of a Lagrangian function to develop equations of motion. I am not able to find anything online. Any help would be greatly appreciated.

In Mathcad 14, I didn't find any functions or worksheets for using number theory functions. I am particularly interested in:Factorization/prime number decomposition of a natural number as an ordered product of prime powers,number of divisors of a natural number,Euler function phi.Are such functions implemented in MC14?Happy New Year, Alfred Flasshaar

I can't install Mathcad Prime 8. I have alredy Prime 7 (with watermark) and it works good. I can download the installer but when i launch "pim_installmgr_mathcad.exe" the installation process just stops after "extracting" window reaches 100%, and there are no installer window open after that.I have tried it many times and as administrator, but always same problem.

I have Mathcad Prime 8.0, and I would like to install it on my new computer. I am okay with uninstalling it on the computer it is currently on. When I installed it on my new computer, I got a watermark across the page instead of just the footer. How can I proceed with installing it on my new computer without the watermark across the page?

Hi, I like to have the date in header automatic, therefore I use the Saved date under Document. I would like to add a format for "Saved date" according to standard ISO 8601, that is YYYY-MM-DD. Is it possible or are there any workarounds for this? Kind regards/Emelia    

I can't find the problem, everything else has been working except this one for some reason    

"This value must be a scalar"Why does the standard lognormal (Pr_lnorm) workbut when I introduce a program into the function definition (Pr_tlnorm), I get the above error?

Hello! Would anybody explain to me, please, how to plot a family of curves given in the attached file?Whenever I define the parameter "const" as a vector or a matrix, the plot fails to visualize. But when "const" has only one assigned value, only one curve (as expected) gets it plot. Best regards,Sergey 

Hello,I have a problem with implementation a license into a server,or more likely reading the license from the server.I transfered a license from one server to another, using this instruction:https://community.ptc.com/t5/PTC-Mathcad-Installation/How-to-Transfer-Mathcad-license-from-an-existing-Host-ID-to-a/m-p/788323#M1599After transfering and implementing it on FLEX License Manager, with help from given instructions,when i install mathcad 15 on my local machine and try to run it, this monit pops up:Movement through port 7788 is open on the server, and FLEXlm service for PTC is up and running,Didn't have any errors through the implementation process, restarting FLEXlm doesn't help.Error no. shown: 96, 491. 

Баг? Хотелось бы пояснение по двум вариантам      Bug? I would like clarification on two options.    Google translate Translated by - Anurag Singh Date - 02/03/2023

I am teaching a class and need the 30-day license. When trying to license Mathcad, I receive a screen message that says I have exceeded the maximum number of licenses for this product type.I must have had Mathcad long ago on a computer that no longer exists. Can I load and use it on this one?

    Hello Everyone.   With referring to Werner's suggestion and Ttokoro's suggestion on solving with MathCad ( or Prime ) https://community.ptc.com/t5/Mathcad/Butterfly-problem/m-p/848009#M204472I'm interesting in it : Given:Let ABC be a triangle with incircle ( O ), and let ( O ) touch BC, CA, AB at A', B', C' respectively. M is a arbitrary-point move on B'C'. Lines BM and CA meet at B''. Lines CM and AB meet at C''. Lines A'M and B''C'' meet at A''.Prove :A'' move on incircle ( O ) ( with M move on B'C'. )      Thanks in advance for your time and help.          Best Regards.                  Loi.  

How can someone with Prime 5.0 open/convert a Prime 8.0 mcdx file so they can open?

Hi everyone We have converted several Mathcad 15 sheets to Mathcad Prime 8 and are now seeing very slow performance, particularly when doing file opening and saving pdf. Opening a Mathcad file, recalculate it and print it to pdf earlier took around 30 seconds per file, now it takes 2-5 minutes. We do not use reference sheetsWe have a lot of programming constructions (e.g. if statements and lookups)We use multi-threading, which improves speed a bit. We don't appear to get the full benefit when having multiple files open, i.e. the engine appears to do calculations in a single sheet at a time and then moves to the next sheetFor saving pdf, we are using the built-in pdf generator (i.e. the Save as command), this appears faster than printing to Adobe Acrobat pdfThe graphical user-interface appears delayed compared to the calculation engine (e.g. when hitting recalculate, the display is not always up-to-date, although there's a green dot in the lower left corner of the window)

Make 1 ohm by 1 ohms is my best electric circuit puzzles. I show the 1D, 2D and 3D lattice answers. Maybe these are the only one solution for each dimension.  Puzzle 28 is using this 3D lattice shape 1*1*2. Where is the most far surface distance point from [0,0,0]? Find the point and the distance.
