Mathcad

Hello, I would like to solve a system of equations, but I receive the error "The symbolic result is too large to display". I need the symbolic result, because I would like to calculate the parameters of the electric circuit for which I wrote this system of equations. I'd appreciate it if you could help me with this issue. I have attached the relevant file. Thank you.Marius  

 

I would like to solve a non-linear equation for the maximum value.  The equation has 2 dependent variables and the solution represents the maximum value for a given number of independent variables. (see equations below). The dependent variables are initialized at the start of the solution and the largest values of Ka and Kp are calculated for the independent variables. I will try the solve block solution with 2 guess variables and see how the results compare to the published solutions.  I would appreciate comments/suggestions if there are other methods of solving the equations.    

My Mathcad 14 files became distort after I got the bigger monitor. Text regions shifted from math regions. Why that happen?Thanks, BR  

Hello everyone!I have been looking into the transient in this passive circuit for some time. However, I see that the theoretical results do not coincide with those using the TABLEAU matrix. As you can see at the end of the worksheet, the denominators are slightly different i.e. L1^2 is missing. Why. Whoever finds the source of the problem is really good.Thanks to anyone who can answer.Greetings.  

How do I give someone access to Mathcad portal?   

clear(all) ?        

I am working on a simple harmonics lab where I need to produce four graphs. I am attempting to graph position as a function of time, acceleration as a function of time, velocity as a function of time, and total energy as a function of time. I have inputted the formulas into Mathcad, as well as inserted the plots.  When attempting to plot the functions, Mathcad produces an error stating that the value on the x-axis must be a real number. (The error is on all four plots)      I have attempted to fix the error by changing the values for t, switching the x and y axis, using T and solving T/20 and 5*T and then inputting those values in for t, as well as working with a few different tutors, but all attempts have not corrected the issue.  Any assistance would be greatly appreciated.   

This is a programming made in matlab I am interested in knowing how this would be done in mathcad more than anything [~,~,CG(:,1)]=unique(Y); this operation, is it possible to do this in mathcad? %CG=zeros(nod,3);%-----------Main Coordinates------------------------------------ --------------------------------------[~,~,CG( :,1)]=unique(Y);%index of unique values in YCG( :,1)=CG(:,1)-ones(assent, 1);ngl=max(CG(:,1));%----------Secondary Coordinates------------------------------------- --------------- --------------- --------------- ----- -CG2=zeros(2,nod-nr);for i=1:(nod-nr)*2ngl=ngl+1;CG2(i)=ngl;finalCG(nr+1:size(CG,1),2:3)=CG2';return   Translated by Andra Chirila using Google Translate on March 23rd, 2023----------------------------------------------------------------------------------------------- Esta es una programacion hecha en matlab me interesa saber como se haria esto en mathcad mas que todo [~,~,CG(:,1)]=unique(Y); esta operacion, es posible hacer esto en mathcad? % CG=c

Can you please tell me if the symbolic math function and symbolic solution feature is still active in the "Mathcad Express" version?

Hi All,New user / buyer of this system where I just got a license.I have an error in activating a license that says that I have reached the max number of license requests available for your product type.Can someone help please?

Hi - I have been using MathCad since ~2002. Over the years, I have grown to love the program and have resulted in literally hundreds of sales of the product now that I am a professor. I (used to) require my students to purchase it for my classes. I continued that practice this semester. Our copies of MathCad 15 ran out in the book store, so I just told them to get the latest and greatest. We ordered 100 licenses of the completely garbage Prime 2.0.I am sorry, but the fact that I can't use over a decade of prior work is a complete joke. I have many licenses of MathCad, but apparently not the right one to even convert my perfectly good files to the garbage Prime 2.0.I have tried to find someone to help me, but there is no useful help that I have found. Unless I get help today, I am going to have my bookstore return the 100 copies of this garbage program and never allow my students to use it in my classes.Seriously, you have taken THE best engineering calculation software and ruined it.

A friendly hello in search of help,Moessner's theorem is well known to me from number theory. It is vividly described in https://en.wikipedia.org/wiki/Moessner%27s_theorem and https://thatsmaths.com/2017/09/14/moessners-magical-method/. I would now like to experiment numerically with this sentence for a change in "practice". Starting from the sequence of natural numbers 1, 2, 3 ... a subsequence is removed from it according to an essentially arbitrary rule (e.g. every third number, square numbers, prime numbers, ...). The sequence of partial sums is formed from the remainder. With the sequence of the partial sums, the procedure is repeated with the same selection rule until it logically breaks off. And that's my programming problem. In MC14 I can't get a handle on the selection, the sequence of partial sums and the repetition as an algorithm, it was always vector nonsense that I don't want to publish here.It would be helpful if I could get a program skeleton with hints using the exampl

Please, what would be the code that I should do, [~,~,CG(:,1)=unique(Y), the unique function was clear to me. I appreciate the answer, now the expression [~,~,CG(:,1)] It seems that it changes the ordered values from 1 onwards, it seems that all the similar values are changed by a number in repeated order as shown in the figure, in the figure there is also the value of ans, which is unique, and above the value of Y=[0,, 0, 0, 3.7, 3.7, 3.7, 7.4, 7.4, 7.4, 3.7, 7.4], using puts it in the first column as [1, 1, 1 ,2, 2, 2, 3 , 3, 3, 2,3], how would that programming be, in Mathcad primeImagen   --------------------------------------------------------Translated text from Spanish to English using google translate.

I have a regressive function Y[k and i need to express it as a matrix. Ultimately, I need to smooth it and make it a continuous function using either linear interpolation or splines. Note that the regressive function is expressed using subscripts, y[k. I'm using Mathcad Prime 

Hi everyone,I m working on a small project. I’m trying to determine rainfall intensity using 3rd degree polynomial equation and regression analysis on MathCAD prime 8.0. If anyone can help me out I will be really thankful.I am attaching a word file for reference.   

Hi,I`m new to Mathcad and struggle with a few things. 1) I try to define a few values, like:Rm:=810MPa (that worked)Rz:=6,3 (without a unit) Mathcad always wants to have a unit. Can I somehow set a value without? 2) When I try to calculate, I get the error "this value must be a scalar or a matrix". I just want it to be a number. What`s wrong? 3) What does Mathcad require here?  Thanks! Best regardsMartin

where is an error?    

Hi, mclicense.exe "I want to configure Mathcad to use FlexLM server", bundled with Mathcad 15 package creates the following registry keys: KEY_CLASSES_ROOT\VirtualStore\MACHINE\SOFTWARE\WOW6432Node\Mathsoft\Mathcad 14\FlexLM\LicensePath Computer\HKEY_CURRENT_USER\SOFTWARE\Classes\VirtualStore\MACHINE\SOFTWARE\WOW6432Node\Mathsoft\Mathcad 14\FlexLM\LicensePath Computer\HKEY_USERS\S-1-5-21-2828309461-2785570631-1443817629-104847\SOFTWARE\Classes\VirtualStore\MACHINE\SOFTWARE\WOW6432Node\Mathsoft\Mathcad 14\FlexLM\LicensePath Computer\HKEY_USERS\S-1-5-21-2828309461-2785570631-1443817629-104847_Classes\VirtualStore\MACHINE\SOFTWARE\WOW6432Node\Mathsoft\Mathcad 14\FlexLM\LicensePath Is there a reason Mathcad 14 and not Mathcad 15 is used in registry hive?

I recently went from Mathcad Prime version 5 to 8, and now I often see errors like "This variable is undefined", where a variable seems to be undefined.However, if I put the Symbolic Evaluation arrow in the line with the definition of f(t) in the first line, the "This variable is undefined" error disappears, and I can plot the function and so on.Can anyone please tell me what is going on? I teach engineering math, and my students are getting more and more frustrated about Mathcad Prime    

In the Mathcad API, about a dozen events are exposed in the IMathcadPrimeEvent2 interface, including "OnWorksheetModified" and "OnWorksheetSaved". I am attempting to access the IMathcadPrimeWorksheet3 property "Modified" within these events. However, when I try to get or set this property within the event, the Mathcad worksheet/application completely freezes and does not allow the code to proceed with getting or setting this property. What's up with that? Is there any way around this? The reason I am trying to get at this "Modified" property is because, for some reason, the worksheet is only considered "modified" the first time after a save, or when saving. Not sure why this was the case.

Using Lagrangian to find the maxima for a multivariable function, solve block wont find a solution, I'm using the solve block to try and solve the functions given by the gradient of the Lagrangian.
