Mathcad

I have a problem with ORIGIN in Mathcad Express 7.  I use the default ORIGIN at the start of a worksheet, do some calculations, then change to ORIGIN = 1, do some calculations, then change back to ORIGIN = 0 and repeat the original calculations.   However, whilst Mathcad reports that ORIGIN has changed to 1, it seems to behave as though the ORIGIN is still 1.   I don't know what I'm doing, or thinking, wrong.   The attached Mathcad Express 7 worksheet may, or may not, show the problem.    Stuart

Greetings Four Fours Game fanatics…you know who you are…(BTW, if you aren't familiar with the Four Fours Game, the attached document includes a complete description)I have been dinking around with the Four Fours Game since Algebra I in 8th grade in the early 1970s, when our teacher, the extraordinary Mr. Sherard, dropped it on us and made it a contest.  In the early 1990s, I began the process of documenting my own hand-written solutions using the Equation Editor in MS Word.  The current version, which I published two years ago to give to my math teacher friends, is still an MS Word/Equation Editor document.  The current version contains multiple solutions for every number from 1 to 300.  I am working on 301–400 as time permits.  There is one source on the internet (mentioned in my document) that has single solutions up to about 40,000 and there was no way I could directly compete with that, which is why I decided to concetrate on multiple solutions for every nu

Under Mathcad Prime 7.0 and Mathcad Express 7.0, this worksheet causes Mathcad to either lock up or to stop running (just disappears) when the first 2 "integrate" function calls (highlighted in orange) are evaluated. The 2 regions are disabled upon loading.   Enabling either region by itself and calculating the worksheet results in an expected message, "This expression cannot be evaluated.  It may have resulted in an overflow or infinite recursion.". Enabling both regions causes Mathcad to fail to respond to user input for a short, but variable period of time, before crashing.   Usually, Mathcad just disappears and is present in neither Task Manager's Process List or Details List. The regions below (in the worksheet) are an extract from a Mathcad Express 6.0 worksheet, which ran without problem under Mathcad Express 6.0.   I'm running Mathcad under Windows 10 Professional on a Lenovo T450p equipped with 16 GiB RAM.     Stuart

How to fix the surface plots? (Excuse me, in preparing the image with Paint, hastily, I made a little confusion but now everything is ok) Thank you very much.

I have a range of lengths. I need to sum them after pushing them through a function. Unfortunately the sum operator is not happy and stating: "Ranges with units must specify the second value in the range". Thank you for your time and help.

Does anybody have the Mathcad 11 Quicksheet colorimg.mcd?  If so, could they please send me a copy?   Many thanks,   Stuart

My younger son pointed out the following YouTube video to me:    It shows an ASCII Art toroid (doughnut/donut) written in C, with the code nicely obfuscated to look like a doughnut.   I couldn't replicate the obfuscation in Mathcad (although my code is usually obfuscated at the best of times), but I did think that I might try to produce the "animation".   If I had Mathcad 15, I could have used the animation facility, but as I'm using Prime 7.0, I constructed a vector of successive frames, instead.   Stuart   I would have presented a more generalized version (eg, user-defined: row size, column size, and perspective depth), but I only have a few more days of the 30-day Trial left, and far too many other worksheets under development to spend upon a relatively undemanding task.    

It's strange where things can lead.  I wondered if a matrix of consecutive integers had a special name in standard mathematical usage.   I couldn't find such a name, but I did find a few with special names, including one called the Lehmer Matrix.   Before I knew what was happening, I'd created a Mathcad worksheet implementing the Lehrer Matrix and its inverse, which has an explicit formula.   The worksheet is attached.  I can't check it properly because I'm about to run out of my 30-day trial period and lose both symbolics and programming.   Stuart

I been trying to change the guess value but with no success.

Dear PTC Community! I am working on a big project for university and it is a requirement to insert the values of any variables into the formulas. I did that by using the symbolic operator aswell as "explicit, ALL". This seems to mess with the calculation results however. My guess is that the symbolic operator is treating the Units as unknowns and therefor not calculating properly.    Look at the screenshot to see the problem!Is there any other way to visualise the values of said variables?Is this a known issue?

I dont have any longer accest to mathcad , i am a student but i didn't buy the licence because i have no money for it , i want to use it free trial please

T(R) -> Temperature is a function of resistance.  Therefore, if I want to find out a Temperature at a specific Resistance you can plug in a value of 10 kohms and get a corresponding value of Temperature -> degrees C.  -> This is Given. 3 Constants are provided and fixed.  They are givens.     Goal -> Rewrite T(R) Equations so that Resistance is a function of Temperature -> i.e. R(T) := ???????   I would like the equation in a format where I plug in a temperature and get a corresponding resistance.   Again I am looking to rewrite T(R) as R(T):=   Can somebody help   

Hello, I need to compare two functions F1 and F2 to get get the variable x, but im new and having trouble with it. Could someone help me. Thank you  

My computer knows not only the calendar date, but also the place where it is!  

Is it one error in Prime (6). In Mathcad 15 all is OK - see please the attach!

I am pretty new to mathcad so working on and learning. Is it possible to get the result from programming in matrix form. I am trying but getting error. Can someone please help   Sam

Hello greatestI bought Mathcad Prime 5 and now I am trying to log in but i could it, can you help me with that .thank you

Mathcad hangs when trying to work on embedded excel.

Lizenz von Schule vorhanden, Anmeldung in Mathcad nicht möglich

I purchased 50 mathcad student edition licenses for the university of British Columbia a few days ago and all 50 licenses are NOT able to download. Access denied is the error message received. It seems the licenses have not been programmed yet by PTC, please change this so my students can download the licenses. case number C16040829 Thank you,Shannon Remillong604-789-5801

Hi everyone, I was just curious as to the various Mathcad 15 VBA based API functionalities. I am aware of the basic functionalities of buttons and utilising the solvers in other software, but I was wondering about the practicality of the following ideas: -Running a VBA macro for excel which will take excel values and generate a fresh Mathcad 15 worksheet with custom equations based on the excel input values (not just filling in inputs in a pre-existing Mathcad, a full from scratch build of a Mathcad document, with scratch built equations) e.g: Simple excel sheet showing the square root of each number from 1 - 100, the macro takes the 1-100 inputs and creates 100 equations in a fresh Mathcad 15 worksheet that square root's the input, speeding up the work of manually having to write out each equation. -A button that takes values from a pre-existing Mathcad worksheet and inputs them into a fresh excel sheet that is formatted via VBA functions encoded into the button. E.g: T

Hi I'm converting my Mathcad 15 sheets to Prime 7 and while making this change I have noted that Excel components in Prime are blurry, so it is difficult to see subscriptions in a table. (Example picture as attached) Is there some way to increase sharpness in these Excel components?   I also have another question about Prime. In Mathcad 15 it was possible to scroll down vectors, but with Prime the results are shown in impractical way. Is possible to get similar result visualization as could be used with Mathcad 15 (Picture as attached)?   Thanks for any advice.

Hello!   My iterative function "blows up" when calculating the displacement, velocity and acceleration due to a dynamic force. I do not understand why since from what I can see everything is correct. Any help is much appriciated and thanks in advance!   Regards Ture

I can't install MathCAD on my computer. Please, help me. I don't know what else to do and I need to try the program. This is the message the installer shows me: "Installation failed, refer to the installation log file for more information. You can Restart the failed application installs or click Exit to close the installer."
