How an I get results for partial derivate in Mathcad prime?  Where E:= V/d*k 

Please see the attached file for more information. This is related to my previous post from 11-Feb-2025. Essentially, I have several single column matrices that when augmented form a table of data. Data for one column in the large table is contained in Matrix A which has repeated values. Thus, Matrix A was filtered (my previous post) such that only unique values from Matrix A were used to populate Matrix C. The minimum values in Matrix B for a repeated Matrix A value were extracted and contained in Matrix D (again covered in my previous post).Please help to produce another matrix (Matrix "Gkeep") that contains the data in an adjacent column (i.e., another separate related matrix called Matrix G) that has the same row entry value as the row kept after filtering for unique values in A and minimum values in Matrix B. Hence, the original large table would be made by augmenting Matrices A, G & B. The summary table would be Matrices C, Gkeep & D.I plan to use this for several columns

to analyse frequency

This request is more fully explained in the attached file. The request is for a way to take two single column vectors or matrices that are effectively two columns of a table when augmented (i.e., namely matrix A and matrix B). The first matrix "A" has several rows that have repeated values. A function has been run to create a new matrix "C" that has removed the duplicate rows.Please help to write a function that will create matrix "D" such that "D" contains the minimum values from the second matrix "B" pertaining to rows that had the same value in matrix A. Thus, matrix D ensures that removal of duplicate rows from A does not lose the minimum associated values in "B". I think the details in the attached Mathcad Prime 10 file will help clarify this request.   

By Ronald Satz, Ph.D.This worksheet will:Solve a common two-circuit physics problem to determine charges and energy, keeping in mind the Reciprocal System Theory and the conventional theory  Apply to Physics, etc.  Perform using electric theory, Reciprocal System Theory, capacitance equations, energy equations, etc.      This paper compares the Reciprocal System theory of the capacitor to the conventional one. Conventional theory posits that neutral matter contains an equal number of positive and negative charges. It also states that capacitors, which are neutral overall, have positive charges on one plate and an equal number of negative charges residing on the other plate. In contrast, the Reciprocal System says that neutral matter is charge-free and that capacitors store uncharged electrons; the capacitor "charge" is actually just another form of energy. Consider an electrical circuit with two capacitors, one "charged" and one not, connected by an initia

i attached the file, its quite the problem. i did the actual movement using the acceleration on solid works. but i cant get my Mathcad graphs to match. i just cant help but feel like its due to my lack of experience in Mathcad. 

Hello!I have installed mathcad 15 on my computer, and am running the license setup. I choose " I want to aquire a license via the internet" and then " Educational-Student" along with the product key i recieved from my university. After logging in in the next step however, when the setup tries connecting to the PTC licensing server, i get a popup with error 403: Forbidden. Please help me resolve this issue, i am certain i have logged in with the correct credentials of my newly created PTC account.Best regards,Jesper

I'm not able to understand, what's causing the error when I create a range. Please review and guide, next step would be plotting with the values. Using Mathcad 10 

I filled the form to download the trial edition (mathcad express) many times, but after 10 days, I never received the link to download the install program. I had a previous version installed but I had to change computer, and the install program stops working at the page where we select the product to install. And now, I cannot download the new version.Can you help me

Hey all,I'm a mech e student using mathcad for the first time for my thermodynamics class.Been having a tricky time figuring things out, and already hit a wall. Not really sure how to figure this out, and I don't recall seeing any previous topic that helped, so any assistance would be appreciated.Attached is a screenshot of the issue.

Hi comunity, I need to calculate an Integral of data vectors like shown in the image.Outside the for loop Mathcad has no problem with convergence, but inside the loop MC returns the error message.Is there a trick here, or is this generally not possible?Greetings and many thanks in advanceMichael   

I have a student mathcad license on my other computer and wanted to move it to a new computer but can't seem to figure out how. At this point I am open to just purchasing a new student license but I also can't figure out how to do that either.

Hi all,I am plotting a phasor (magnitude @ angle) on a polar plot in MCAD 15.  I'm doing it in 15 because I want to make an animation as the phasor changes.    Here is the output: https://relayman.org/temp/e/output.mp4 The red dot you see moving around in the video is the endpoint of the phasor.  What I would like is for MCAD to leave a red dot at each location along the way - so in the end I would have a plot of the locus of those endpoints.  Something like the attached image. thanks  

Hello everyone!I’am trying to solve an optimización problem using minimize function but get an error “This variable is undefined”.What am I doing wrong?CarlosRomero

I can Install M15 on Windows 11, it does basic calculations, but will not insert controls or links to spreadsheets. No error messages are given. It ran fine on my previous laptop running Windows 10. What is missing ?

The solve block is not finding a solution. I'm using Mathcad Prime 10But using the same formula I can iterate a solution I think is convenient enough. What am I doing wrong?I though maybe changing TOL or CTOL would be the solution but no.  

ok.  something you just need to reach out to the power users.   I'm working in Prime 8 and have a simple spread sheet.  not knowing all the available size if I enter a number, I should get the nearest available number to pull data.    This should be simple right.  

Hello everyone,Could someone help me figure out why the options in the outputs of m and n programs are repeating, while the program k works fine? Is there anything i should change in Bop() function?Attached the Mathcad sheet.

I'm trying to write a program in Mathcad, but stuck on this step highlighted below.How to insert the second line in the bracket as show below for return function, thanks 

I need a program that is able to solve compicated mathematician problems

In the attached file below if i give sub = stack(sub,RA) at the end of program, it gives same options multiple times. could someone please explain, why the program does that?can't attach Mathcad sheet. 

How to apply this program, when the vector has two columns.   Reference topic: https://community.ptc.com/t5/Mathcad/How-to-remove-duplicate-entries-in-an-array-using-a-program/m-p/996692 

Is there a way to transfer the software from one computer to another computer? I have upgraded to a new computer and would like to transfer the software.

I am using Mathcad Prime Release 10.0 and Datecode10.0.0.0Good day,How to do automatic "step by step" calculation in MathCAD where in it captures every steps in solving a certain equation.
