Mathcad

Mathcad has many functions and constants named after mathematicians and scientists - Chebyshev, Runge, Kutta, Kelvin, Sinus, Ampere, etc.But I did not find there the name of the greatest mathematician - Euler. We need to fix this and make the Euler function built-in Mathcad for the simplest numerical solution of the ODE.Especially now, due to the high calculation speed, there is a return to simple algorithms - KISS!

I am new to Matkada prime, I have a problem with solving problems when I put symbols (explicit, all), I have a lot of numbers in an explicit expression after the comma, how to reduce them to at least 3

Hello, I need some help solving this problem: Given matrix A(n,m). find the row with the most negative elements and replace it with the row with the largest element of the matrix.   Thanks!

Здравствуйте, у меня есть одна проблема при вычислении, когда я ставлю символьные операции (явные, все), у меня много значений после запятой.how to make it so that there are fewer of them, for example 3   Hello, I have one problem when calculating, when I put character operations (explicit, all), I have many values ​​after the comma. how to make it so that there are fewer of them, for example 3   Translated by Iuliana Lazar with Google Translate on 23 Nov. 2022

Hello,I want to plot some functions:   And the function f2(t) should look similar to the function f1(t), not exactly, but something like f1(t) looks.   The problem is that the graph of the function f2(t) is displayed only when I increase the time axis so much (10^1, 10^2, 10^3, etc), which is a bit much because I want to see this part (see image below) from the beginning as it looks, not a straight line   And not like this (see image below), because I want to be able to see the transient/beginng part much more, how will look (like the image shown above) Good: Bad Bad   I would like, if it is possible, to plot both functions on the same graph and to be able to see the beginning part for the function f2(t) just as I can see it in the case of the function f1(t)   Mathcad Prime 7 file attached.Thanks.  

Hi all,I need your help.I have an old calculation, which was made in Mathcad 14. This calculation was made not by me.This calculation perfectly works in Mathcad 14. Now we have Mathcad Prime 7 and 8.I have converted this calculation to  *.mcdx format. And I got a problem.The equations, which calculated using Euler method, cannot be calculated now in Prime 7 and 8 with step  5000 and more.It show me error “ infinite recursion or overflow”.With step 4700 it still works. Attached you can find this equations. Thanks in advance.

Hello.Could someone help me, please, with this task? An error while trying to find Symbolic solution of a system of linear equations with specific accuracy. What I should do make it done?

Hello All, I am relatively new to MathCAD and am having an issue developing a set of symbolically solved equations for a system. I have assigned values to the variables however throughout my analysis I would like to solve or simplify equations ONLY symbolically for a particular variable and KEEPING all variables as symbols, NOT replacing them with their numerical values.Is this possible?

Hello! How can I sum all the values given in a table by using the Summation operator? Each row is n=1, n=2 and so on.Please, take a look at the attached file.

Hello.  I'm new to Mathcad, and I'm trying out some symbolic variable definitions.  Can I define a variable like this? : I have tried to mimic the w^2 term, but I am unable to set an assignment statement. Thanks in advance.

Obtaining the ASYMPTOTIC Bode plot for the following transfer function: Mathcad Prime 7 result:   Why does the result in the Mathcad Prime 7 not look like it looks like in the figure in the example??The idea is that I want the plot in Mathcad Prime 7 to look exactly like in the picture above, with straight lines and those corners, and not to bend corners Mathcad Prime 7 at w=2 and w=10.Mathcad Prime 7 file attached.  

Hello,I would like to ask if it is possible to interpolate a value between 2 plots or more as shown in the picture. For example, I want to get value of GHh for H=1.5 m and dimeter 6 in.  

Hi all,I am new Mathcad user and stuck in using matrix in an equation. I have equation X equal to other variables, one of them is Z which is varying in intervals. I put Z in a matrix, as showing the pic.  I want X  outputs in values or matrix, but mathcad show an error.Is there a way that can form it to get X values based of z values rather than using many separate equations?   

To all I am looking at the ODESolve with a “saw tooth” input (y’’) and I get a very spiky response – see attached (mcad 15 wsheet will follow)Why is that?Tried different time steps but always get this rather spiky response ThanksJohn

The company I work for just updated from Mathcad prime 7 to Mathcad prime 8. Is there a reason why it is so slow? Is there any suggestions as to remedy this?With version 7, if I changed a variable it took less than 5 minutes for it to filter through the worksheet and I was still able to scroll with relative smoothness. Version 8 is horrible! It is taking 2 to 3 times as long for the same worksheets to filter through, scrolling during this is virtually obsolete and it will crash unexpectedly,Can someone from PTC answer why version 8 is this way? What are the steps being taken to fix this? 

As per this thread - same issue.   Hi Chris,   I have recently started using MATHCAD but, still be able to relate with your problem statement.  I would really appreciate if you can share your method to work on this project.   Thanks, Srushti 

I am trying to get solution for equation getting error 

The attached file is corrupted - Element content is incomplete according to the DTD/Schema, Line number 1134, Char Pos 21. Can some one offer suggestions on how to fix the file?  

Hello! Would you, please, point out why I can't evaluate the symbolic expression of of the r(x,0) function while d(0) is possible to evaluate? Those are identical expressions but by some reason Mathcad evaluates correctly only one of them. It is inconvinient to introduce new function such as d(t) to compute r(x,t). I marked equations by the blue colour. Best regards,Sergey

For units within plot I am getting error this variable is undefined. Can someone please help what I am doing wrong in this 

Hello:I have attached a Mathcad file. I am unable to open this file . It says "element content is incomplete according to the DTD/Schema". Thanks in advance!!

Hello. Is there a way of obtaining the Fourier Series of a function f(x) symbolically (file attached)? Best regards,Sergey

I am tring to set the starting value of the summation as below. Prime 8 file attached. Want to be able to set k=r or k=0.  

Hello, Why solve block is unable to give the maximum value?
