Mathcad

Help me please with this problem! Thru ODEs solution - see please the attach Prime 9 file. See also Great-Comet-of-1811-ODEs-solution 

I need to make mathcad to choose the minimum value when it draws the plot. The next value can't be bigger than the previous value?Please Help  

Hi.First post, LONG time mathcad user...on prime 9 now.I'm trying to fit a fairly routine function to some datapoints using genfit.I don't see where this is going wrong.genfit basically treats the guess value for 'a' as a hard constraint.So whatever I set the guess value to ('3', below), the fitted function asymtotes to that value and does not adjust 'a' to fit fit the data. What am I doing wrong?Many thanks in advance. 

Building stiffness matrix I needed a function to add one smaller matrix within a larger one. I've added some functionality to that just out of interest. Now the second one can be added or it can replace the first. It can also be fully or partially outside the first and the original matrix can either expand or the latter matrix can be cropped. Seems to be ORIGIN-neutral too. No guarantees, so test it first. Have fun! Mathcad is Prime 9.

hello,im trying to get best wey to round numbers with units like 5.123456789 V im using the function round(x)but shows error for units not compatible need to use the rounded value to show on summary resultsright now im using this functions to round and display the results   but this basically remove the units and convert my variable over and over to number and string, to be able to display it as result.as you can see below but i want to show that result is actually 3.33 V I also have calculations for current, and capacitance, so I need function to keep different used units. 

I want to insert huge table with 1339 data in mathcad without using excel . I need the values to be in the mathcad sheet but I don't want to have many pages. Is that possible? I don't want to have 38 pages  Can I just show the first ten rows ?  

Has anyone managed to install MathCad 14 on Windows 11? I thought I had done it, but various things are not working. For example (this is from my from my Windows 10 installation) On the Windows 11 installation i =  produces nothing; i.e. no table.  

Hello, I tried to download Mathcad Prime 7 but in the installationassistent the status of the application is "not permitted". How can I avoid this? 

Hello,  I am using PTC Mathcad Prime 9.0 and really need to extract the all values of Sol Data of differential equations in Mathcad to Excel or CSV files.I can only do make the graph with the data.Your help or advice for the method will be very appreciated. Thanks

Dear forum,Does anyone know what the error is and why it doesn't give the result I expect?Regards,CarlosRomero

Continuing the topic Plane, sphere & cone  When I was a student, we solved the following problem in a class on descriptive geometry (now it’s engineering graphics). There are two triangles in three-dimensional space. Triangles intersect. You need to draw triangles in stereometry and in three projections. The triangles are colored - one red and the other blue. It is also necessary to draw a segment of their intersection.Can this be done in Mathcad? Better than 15th. I hope someone will enjoy solving this problem. And remember your student youth. PS I did all this without a computer, of course. I first drew on whatman paper with a pencil, and then outlined everything with drawing ink.  Then I removed the pencil lines with stale bread. There is a brilliant story about this. Witches' Loaves by O. Henry Miss Martha Meacham kept the little bakery on the corner (the one where you go up three steps, and the bell tinkles when you open the door). Miss Martha was forty, h

Can the pdesolve function (Prime 9) work with units? See lease two sheets in attach

I want to multiple these two matrix without summing the answer. Like the first value of q times the first value of A and the result should be matrix not a final result 

I want to merge to metrics in only one metric, m should contain the values of both q and As 

This is also puzzle of youtube. And not question. Anywaw, Mathcad can solve.  

I am unable to get odesolve working in my worksheet could somebody help? 

Hi my Mathcad 9.0 shown "you have reached the maximum number of license available from your product type.how to fix it? i used to free 30 days trial.

New to Mathcad, running into an error I can't resolve. I have defined all of my matrices and variables up top, but in the solver block there are unrecognized variables. Error is: "This variable is undefined. Check that the label is set correctly." Anyone have an idea what might be going on? See screenshot below.  Using Mathcad Prime 9.0.0.0

Hello.Im using Mathcad prime 9.0.0.0need to create an analysis in which im comparing my results with my requirements.need some kind of function to do that but not really sure where to start or what to look for. something like my maximum voltage calculated is 16V, but per requirement im allowed to go up to 18Vso want a function that compare this 2 values and show them like:"Result: 16V  -  Margin: 12.5%  -  PASS"   

I want to solve three equations with three unknowns and display the solution on a 3D graph with two points - the roots of the equation.I can’t find Vyacheslav Mezentsev’s utility (Mathcad 15 or Prime) for such drawing two close surface. Help please.

All the variables are defined , However I couldn't figure out why it is not working 

Happy New Year!     This month’s challenge is based around statistics, specifically permutations and combinations around shuffling a deck of cards. It’s inspired by this article: https://www.mcgill.ca/oss/article/did-you-know-infographics/there-are-more-ways-arrange-deck-cards-there-are-atoms-earth   Your challenge, should you choose to accept it, is to perform the following in Mathcad Prime: (Basic) Calculate the number of ways to shuffle a deck of cards. (Standard 52 card deck, no Jokers). (Basic) Calculate the number of ways to shuffle a deck of cards if the suit (heart, diamond, spade, club) doesn’t matter. Calculate the number of ways to shuffle a deck of cards consisting of just the face cards (jacks, queens, and kings). If you could shuffle the deck one time a second, how long would it take to shuffle each possible way? (Express the result in hours, days, or years, whichever is easiest for people to grasp.) How long would it take to shuffle the face cards until

Hello,

Similar routines also were posted here from time to time and a command like this should be part of Mathcad/Prime out of the box. Unfortunately it isn't. I see that the topic is from 2016 and it is now 2024 but i had basically the same issue. Have i to conclude that it is still not fixed to create easy a vector in some range?   ----- Initially posted in this topic

Dear ladies and gentlemen,   We have 2 Mathcad licenses, but I can't find the product code for them right now. If you need any more information from me in this regard, please let me know.   We currently have the situation that we have 2 licenses and had to change the MAC addresses for them and reinstall them at the same time. Now we are faced with the issue that Mathcad 15 can no longer be licensed with the current licenses because Mathcad is too old.   So my question to you is, do you still see a possibility of getting Mathcad licensed despite a new installation, or are the licenses no longer usable for us in combination with Mathcad?   Thank you very much for your effort.   R. Bürger   Translated by the Community Moderation using Google Translate ----------------------------------------------------------------------------------------------- Sehr geherte Damen und Herren, wir haben 2 Mathcad Lizenzen, den Product-Code dazu finde ich aber gerade nicht.
