Hi! How to solve an equation with a complex variable.G(s):=1/[(s^2)*(s+1)^2]; s- complex variablelike this does not work: solve,s,assume,s=complex|G(s)|=1 ----------------------------------------->0.682 with respect Fynjy....

Hello,I'm sure this has been answered before, but I'm wondering why I am unable to plot two vectors while I am able to plot another. I'm unsure of the tecnical reason why. I would appreciate any help with the issue. Page 3 currently has the plots that are not plotting correctly. I have also put some plots on page 4 showing that I don't think it should be the fault of a range being used.

Hello,my question is inside the mathcad sheet. it is about when the value is odd to return a certain value, and when it is even to return a different value. Thanks!

Does anyone have a Mathcad Prime script for rainflow cycle counting for fatigue analysis that they would be willing to share or can anyone point me to an existing respource. I have several spectra I need to convert into stress histograms. The spectra each have more than 20,000 lines of data

Please,I need export results of functions to a vector or Excel table. I can not work with vectors instead range variables because I have a lot of functions depending of these range variables. After made calculations, I have a function results (with a lot of singularities) and I need find max and min values from these results. I need convert these results to a vector, so, I can use max and min functions to find the maximum and minimum values or export these values to Excel.Someone have any solutions to this case? Thank you.

Hello, everyone!I've noticed that there is a friendly and helpful community here, so maybe you can help me out with my issue. I'm solving a differential equation with odesolve command, and everything works no problem.Now I'm trying to add a periodic square wave function with variable duty cycle into the equation, and everything gets more complicated. I've used two similar methods to define the periodic function and they both work almost the same.The trouble is - with bigger values of duty cycle it works flawlessly, but as soon as I try to lower it, it seems that odesolve misses some values and the solution looks obviously wrong. My first guess is that it is a numerical problem, as the equation also contains some relatively small and big numbers, changing some of which also helps a bit, but that's unfortunately not an option. Maybe there is an option to use some other method besides odesolve, or any other trick to fix this behaviour?All other comments and graphs are in the attached file

I have a problem with formating. If I write a handout, documentation, article etc., I have to write formulas. If there are varibles in this formulas which haven't been used before, they get marked with a red box. Doesn't look very pretty. Is there a way to turn this off ....Thx

Okay, how can I plot in degrees Fahrenheit?

helloi have been having this problem when solving an equation, i think im doing everything ok, but when i use the solve function i returns like a numeric equation with units, anyones know how to workaround this one?

To allI created an e-book following explanation in manual and it works fine. I am looking for a way of having the folder where I store all the mcad files of interest not in the MathCAD installtion directory (...\MathCAD/MathcAD 14/Handbook/ ) but in a totally different folder. I cannto find anything in the manual about that. (Probably not reading properly I guess!).ThanksRegardsJXB

Hello there.Here I am again!I've really been searching on this subject, but I can't seem to find out how.In this arganddiagram (I've found it on the internet)A line is drawn from the origin, to the coordinate, and the angle has been drawn too.How do you do this (either in MC15 or prime) - It would really be great, as I have an exam on the subject monday :-)!Thank you,Ben

Hello there!Since I've been around these forums earlier, I've been conviced to work with mathcad prime 3.0!At the minut I'm doing som old tests, to see what problems i might face.I faced one! 🙂I apologize for the language - it's danish.As you probably already realized, z2 should be going around in a circle - but I have no idea as how I'll make mathcad do that!I really hope some clever heads in here, can help me out!Have great day!Ben

Hello,i am wondering if is possible to make automatically content in Mathcad 15 like in Microsoft word? Anyone has expierence with that?Thank you

I am trying to translate some Matlab programs into MathCad. My question is highlighted below and the worksheet is attached. Thanks in advance for any help.

Hello Mathcad community!I'm unexpirienced Mathcad user, but I was able to solve all my problems and misunderstandings by myself. Till now.I'm trying to analyse the experiment results of electric field measurement. I wanna convert the result into frequency domain by using Fast Fourier Transform (FFT). I had done some programming in Mathcad prime succesfully, but now I can't find where my mistake is.I'm attaching sheet and imgs.Thank you for any kind of help.PS.: I'm using Mathcad Prime 3.0

Is it possible to insert an Autocad figure into Prime in a similar fashion as was done in Mathcad 15? Not copy and pasting, but rather inserting a CAD figure which you can double click and open to modify within the Prime software. It would be similar to inserting an excel component.

Hi All,I recently formatted my laptop. So I sent PTC support for new licenses to install these two products. However when I receievd the licenses, I installed them in the respective MathCAD folders in the C Drive of my laptop. When prompted for licenses by MathCAD software , I point the software to the license path. But still neither MCAD 15 or Prime 2 works. I have tried all ways, but this licensing system is a big draw back on MCAD. This was the same issue when I tried to install last time also. PTC need to work on a simple mechanism to solve the licensing issues. I have other software, and not a single software has these kinds of licensing issues. But MCAD seem to be a totally unproffesional software (not to mention the poor reviews of Prime1, 2 and 3 and their functionality). I wanted to upgrade to Prime 3, but due to the poor reviews and without any necessary improvements, I had put the upgrading on hold. Coming back to the point, can someone advice me on how to have a smooth inst

Hi After installing mathcad and starting, it prompts for getting the licens file through the internet. When I give my user id and password it gives a message "The remote server returned an error: (407) Proxy Authentication required". What to do now?Thanks in advance

Hi Mathcad Members, I wanted to reach out to you and ask about the number of sub-communities that currently sit under the parent community that is Mathcad. Currently there are 16, yes 16, sub-communities. Quite a lot in my opinion. Many of you described this as being difficult to navigate.With the current community functionality, we can solve this navigation issue by consolidating the 16 sub-communities down to a manageable 5. Don't worry, your posts will remain intact and no data will be lost.The top 5 sub-communities based on popularity are:Mathcad UsageMathcadProgrammingOther SubjectsCalculus & DesI almost feel that Mathcad Usage, Mathcad and Other Subjects can be consolidated into one sub-community simply named Mathcad. It will be general in nature to capture discussion not specifically carved out for things like Programming, Calculus etc.What would your top 5 Mathcad communities be?

Problem I have is that I am solving for 12 variables using Simultaneous Equations. This I have done. However, now I want to change one of the constants (theta) several times to specific values and solve the Simultaneous Equations for each value of theta. I have tried to give the initial values of the variables several values in matrix format along with the several values of the constant and this did not work. I also tried to give the inital values of the variables with respect to the constant along with the several values of the constant and this also did not work. Attached is file without multiple values of theta since I couldn't get it to work.Help PleaseSteve T.

Hi all,I have a system of two coupled second order ODE equations that I would like to solve symbolically. I have checked Mathcad' quicksheet and browsed this forum, but to no avail. Most of the information I find is on numeric solvers. At first glance I though it could be done in matrix form, but then I don't know how to go about.Is this at all possible? Can someone lend me a hand on this?Many thanks,Newin

Hi!At the end of the attached file i have two functiion, the first seems to work fine the second is similiar but doesent return a value. The graph seem to wok tho, why?Thanks in advance!

HiI have a MathCAD sheet that applies a function to a range variable.e.g. t:= 0,0.001..1 x(t):=2 * tHow can I then convert x(t) into a vecor e.g Y:=x(t)ThanksScott

HiIn Mathcad 15 it was possible to split up an equation by CTRL+ENTER so it could fit on a single page but i can't find that option in Prime 2.0..Hope somebody can help?
