Mathcad

Good morning,I recently downloaded the trial version Mathcad 15 M045. This is the problem:when it evaluates a symbolically expression i have to insert "->->". Why ? Thanks a lot

I'm trying to write a transfer function of LRC filter but when i want to plot on XY graph i receive an error message.Seems that the product between an inductance and resistance value is problematic.Could you help me?

Hi, I am wishing to solve a Hertzian contact problem for sub-surface stresses for multiple points in order to plot contours. The solution routine uses Polyroots to extract the maximum root for use in the calculation and works fine for a single point. Is it possible to automate the process in a loop for variable x, y and z using Polyroots? I tried a couple of attempts but get errors.Any assistance would be appreciated.Thanks Ross

Hello everyone,I am working with Mathcad Prime 3.1, and I use the solve block.The problem is with the function find:  I want to specify directly (like in Mathcad 15 with the index) the element that should be reported. I don't want to report all the matrix and I don't want neither to use an extra variable to report the specified element of the resultant matrix.Thanks for your support,Best regards,Nadia

Hi All, I am trying to solve a geometric problem. A typical geometric series can be written like this, where N and M are two commensurable constants, i is the imaginary unit.  For this kind of geometric series, it can be derived by hand that it is equal to If we are trying to solve this expression, by introducing a (k-1) as a coefficient of the exponential function, how can we solve it? It is not necessarily to be done by Mathcad. Thank you!

Why can't I Print my Mathcad 3.1 file to PDF file?

I am new to MC 3.1 and struggling with units.  For instance, how do you input the units for the coefficient of thermal expansion - 1/F or 1/K?

HelloI have been using MathCad 3.1 for about 5-6 months as a tool for calculating and taking notes in physics, math, electrical engineering and so on. Most of my .mcdx documents contains a wide variety of text, calculations, plots and images. Usually I have no problems with MathCad. However i cannot open a specifik file containing valuable notes on electrical and magnetic fields. The content is valuable to me, mainly because my exam on the subject is in 2 days, but I can get by without.But I would really like to know the cause of this problem, because if this is a consistent problem and i will, for no appearent reason, loose some files every now and then, then i cannot continue using MathCad. It could completely ruin and exam.The nature of the problem:I have not opened the file for at least a month. It worked fine the last time though. Now when i try to open it, it says "The file type is not supported" and it points to a log file. After searching for a solution on the internet i found

Hello everyone,I am working with Mathcad Prime 3.1, and I need to create a matrix 16*12, But I find that the maximum of rows to create is 12 and I need 16 in my case.Is there a way to solve this problem.Thank you so muchBest regards,Nadia

I am currently working with Mathcad Prime 3.1 and I need to write the percentage % in a subscript of a variable but it doesn't work.I want to write the sign % after 0.5.Many Thanks for your support.Best regards,Nadia

Hey Guys,recently I got a license for Mathcad Prime 3.0 (Academical Version) and tried to install Mathcad on my PC.I had no problems with installing or licensing later on.First startup also no problem.But when I am trying to do something with it, it starts freezing and there is no way to get control back.Mathcad is working on the devices from class mates using the same Operating System.System Specs (might help you):Operating System: Windows 10 Home 64bit version 1511 (build 10586.218 for the nerds ^^)16 GB of Ram and nVidia gForce 960mand SSD for operating driveThings I tried already:.) Run in compatibility mode in windows 8 and 7.) Reinstall with all Mathcad data removed.) Install with license.dat.) Run over internal graphics card (Intel HD 530).) Run as Administrator.) Installed Framework 3.5 and laterSomething else I can try?Hope I havn't forgot something and also hope for a fast help.Greetings AlexanderBtw.: The reason why I am using Mathcad Prime 3.0 and not 3.1 is just because I

Mathcad 15 will let two users open the same file without warning.Mathcad 2001 would warn you if a file was in use by another user.How is this even possible?

Hello,I need some help regarding the unit °C in prime 3.1. In fact, when I extract the variable " Tjmax_D367" from an excel table created in Prime3.1 and when I want to define its unit which is °C, It doesn't work. The error is: "This value must be a scalar or a matrix"When I try it with the other variables extracted, it doesn't work too even if  The unit "V" and "K/W" work fine.I will really appreciate your help,Thanks in advance.Best regards,Nadia

Community....I am attaching a worksheet requiring the use of a hypergeometric function 3F2 as may be seen. I am at a lost in setting this up in Mathcad 15.Anyone that can help would be greatly be appreciated.ThanksDick..

Hi,I am creating a simple 2D plot, where I want to reverse the y-axis to be shown downward. Prime 3.1 sheet attached.In MathCAD Prime 3.1 -> How is it possible to inverse the y-axis to increase downward. Hence - top value on y-axis is 0 and bottom value is 500? Thank you in advance!Anders

Obtaining the minimum and maximum value in a matrix is easy due to you can use the functions min and max.but i need to obtain the matrix element that contains the minimum and maximum value inside the matrix.Thank you in advance,Rogelio

Dear Friends,I know, I might know it, but I would like to ask.

I'm facing a problem related to matrix element used in a program . I'm attaching a math Cad prime 3.1 file .
