I 'm busy with calculate the intersections of two lines as done here.  I think the variable y2 is currently the problem because it is a single value. In python(with numpy) i'm able to create a ones(length) array. How do i create a array (arbritrary length) where all values are the same?  

Hello, Thank you.Mathcad Prime 7 file attached.

Hello, Thank you.Mathcad Prime 7 file attached.  

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

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.  

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.   

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

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 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.

When I am writing a program that won't fit on one page, the program continues onto the next page.  When that happens, I lose program visibility.  Portions of the program are lost in the header.  What can I do to subdivide a program so that none of the program visibility is lost in the header?  Is there a continued statement that I can add to a program without losing functionality?

Hello, up to now I am using MathCad 15, and there I use the feature of the two calculation runs:1rst run: using global definitionIn this run I put all of my calculations, which usually requires re-definition of global parameter. 2nd run: using "normal" operatorsIn this run I put results, plots etxc. The big advantage is that I can place# all parameter definitions at the top of the sheet# all results just below the parameter definitions# all formulas below the results In Prime this seems not to be possible any more, as a global parameter can only be defined once.Now I have 2 issues:# how to place results at the top of the file ?# how to convert my MathCad 15 files? Hope that someone can helpChristoph

We have a circle with r=10 cm. Solve the blue area of Octagon and Square make the shape.This is able to find without trigonometric function or Junior high school knowledge.But we can use Mathcad to solve.  

    Hello Everyone.From the following :      Thanks in advance for your time and help.          Best Regards.                    Loi.
