Mathcad

Is there a way to use plot phasors of voltages and currents (complex numbers in rectangular or polar form)? I would like to do this without creating custom functions, if possible.

I've imported a MathCAD 15 document into PTC Mathcad Prime 7.   I want to add grids to the plots.  I don't know how.  The documentation doesn't match what I see in PTC Mathcad Prime 7.   Not sure what to do.

Hi all trying to get a mathcad function that returns an rounded match from a table the example is attached, I could put the figures within a graph and use the interpret function but i want a rounded answer to the next D610. i.e. for the attached sheet the solution would be 1.7m when the looking for an F of 27kNm in column F610  i.e. not an exact match, therefore selecting the higher value in column D610. i.e. in excel this would be a Vloop/match function.   ThanksBen 

I am getting very strange error in Mathcad Prime Has anyone seen it. If yes how to solve this and where I am doing wrong 

Is there  a simple way to display a complex number in polar form (that includes the angle operator) without manually finding the magnitude and angle? 

Whilst playing around with the Is Element Of operator in Mathcad Express 7, I noticed the following:     I was surprised to see that Mathcad thinks that NaN is a Real (and hence Complex), but not an integer.      Is this just a case where one should expect inconsistent results from applying non-NaN-specific functions to a NaN?  If so, I think there should be a warning about this behaviour on the Is Element Of Help page.   Or is it something that should be corrected?   The red error arises because only the symbolic processor can test for rationals and Mathcad Express doesn't have symbolics.  Consequently, I don't know whether Is Element Of's NaN behaviour extends to symbolics.   Stuart   I discovered the above whilst trying to write a couple of data type identification functions.      

HiI am currently converting files from 15 to Prime which must of it have been successful.I have an issue with this equation below:Here are the input:I can plot the data easily, but I cannot get the intersection point which im trying to with the root function.It works in mathcad 15:    

I have created a vector that has both positive and negative values. I would like to sum all the positive values, return the number, and then separately sum the negative numbers and return the number. Is this possible? Thanks,  Ross 

Hello Experts, I am pretty new to mathcad and unable to understand what I am missing in program I have written.  Any help is appreciated 

I have two ode's that have a parameter. When I set the parameter to zero some (but not all) the solvers give results that might be reasonable. But, if I make that parameter a very small number, none of the solvers work even though this would not seem to make the equations parthological. Does anyone have some insight to what is going on? Thanks.

Hello, is it possible to convert MCDX-files backwards to MCD-files? Best regardsMichael

Hello! Is it possible to create at worksheet, where when you open it, you have to save it as a new worksheet?

Help me, здуфыу! Suggest good Mathcad expressions for numbers 13, 14 ... 24 For Mathcad-24s-Clocr. Mathcad-12-ClockNot Mathcad 24 clock

I encounter the wrong output of the calculation.Equation[x y z] := [x=A, y=x, z=sqrt(x)]T --> solve,x,y,z,Of course sqrt is input as mathematical root actually.The output becomes;[A A 0]The z value is wrong.How can I fix this?

I wrote the program which fit two datasets by the same ODESOLVE and miner. But I call the function twice and the program works slow.  So anyone knows how to make it faster to fit two datasets?    

I'd like to suggest vectorizing the functions num2str and str2num.        I've had to write vectorized versions of these two functions to allow me to evaluate array expressions as arguments (I can't explicitly vectorize over num2str or str2num when using such expressions).     What evaluation reasons might there be that would mitigate against vectorizing these functions?   Stuart

Today marks the 200th anniversary of the birth of the great writer Fyodor Dostoevsky - Wikipedia In my book 2⁵ Problems for STEM Education - 1st Edition - Valery Ochkov - Rout (routledge.com) I have solved (with Mathcad of cource) one problem from one Dostoevsky novel. Do you know this novel? Do you know this problem? What Dostoevsky novels do you know? What Dostoevsky's novels have you read?

Hello everyone!I would like to draw the attached graph in 3D with Mathcad 15. It seems to me that this problem has already been addressed in the community but I cannot find it. In fact, it is a rather arduous job although from the geometric point of view it is a question of tracing flat surfaces orthogonal two by two. To do this, I downloaded and installed "images14.exe" and also the list of the functions contained, but I don't know how to use it. How can I avoid using these functions? Could anyone help me? I thank him infinitely.

We are obliged to use only SI when writing textbooks, reference books, articles, technical reports atc. And in this system there are no units of information. How to solve this problem? That's how!

In my entire life, I only wrote once Mathcad-sheet with ORIGIN not 0 and not 1. Questions. Do you have own Mathcad-sheet with ORIGIN not 0 or 1? What ORIGIN was in my Mathcad-sheet? What is it this my Mathcad-sheet? You can find it here 2⁵ Problems for STEM Education - 1st Edition - Valery Ochkov - Rout (routledge.com)

In Russia, Roman numbers are used even by not very literate people. One example.The log house needs to be moved to a new location. Before disassembling it, the logs are numbered in Roman, not Arabic numbers.   Do you know why? Choose please the correct answer! 1 The carpenter wants to show his high culture - knowledge of antiquity! 2 The carpenter cannot count, but he has a clock with Roman numerals on his left hand. He looks at them and numbers the logs. 3  People who are assembling this house in a new place may not know Roman numbers. But such a program will help them! But this program has a small defect. Can you find it and fix it?

It will good to have in Mathcad new temperature units. Allen Razdow will be glad!

Hello everyone. I tried to solve the equation with several solutions. Probably the solution given by Mathcad 15 is correct. However, the Prime7 method of entering equations in a matrix does not give a solution, and the Solve Block method gives a numeric value, which is probably incorrect. I attached these files. Please advise.

There is an old philosophical parable about how one user was waiting for a new Mathcad for a long time and rebuked PTC, telling the company that the Lord God created the world in seven days, and PTC was busy with Mathcad Prime for a whole year. PTC was not at a loss and answered like this: "Look at this World and look at Mathcad!"
