Hello maybe you can helb me with my Host-ID. I am new at mathcad and so I have a question to the licensing. First I had to log in and then I have to enter the productcode and pick a Host-ID. 2 different Host-IDs are suggested but I just dont know for what I need it and which one I should pick.  

Hi all, How should I do to modify my article in mathcad blod ? Thank you

Hi all, What happens? I write a question, but it does not appear in the list. I want to answer a user's question and after posting it, the system responds that the answer was successful. But then it is not anywhere. Why? Who can tell me why and what should I do? Thanks MF  

hello, I am trying to find a way to use variables from sheet to another sheet without having it to define it in the new sheet. Is this possible? for example in Sheet1, I have VCC = 5V, I want to use VCC in the new sheet without needind to re-define.   Thank you, Hector Torres

Hello Everybody,i have a question about Mathcad 14. How can i solve a System of n equations that has all equations in the same form likeEquation i: Q_i = k_i*A_i*DT ....when DT is a constant, all Q_i and k_i are given.How can i do this directly? I dont want to write all equations down, coz i want to keep the number of equations as a variable.ThanksLert

Hi guys, can you help me identify the problem in the input? All other variables are defined and i keep getting the "Invalid constraint" problem.  

Hi everyone, please how do i add legend to contour and surface (3D) plots with Mathcad 14

Forgive my ignorance I'm very new to this system and currently trialling it.   We are looking at some calculations from International Standards and struggling with the MathCad recognition of the units.   When I set the unit value up as Watts/m*°C its constantly highlights the °C in red and tells me it should be a scalar or in a matrix, which I'm still trying to understand the link to this?   I can get this box to go away if I replace it with the symbol ∆°C, which then allows the calculation to function.   The only problem then is the result from the equation should be in W/m*°C but the calculation keeps forcing a K, )which I'm guessing is Kelvin) to the front to the units which then causes problems with another calculation as the units become undefined even though they are a result of an equation?   We end up with K*W/m*°C, and the answer should simply be W/m*°C?   Not the worlds best mathematician but struggling to understand why the programme forces a ch

My expfit equation is not plotting. I am getting an "undefined variable" error. When I backtrace the error, my modified expfit equation tells me that "t_e" is undefined and to check label is set correctly. On the plot, the array dimensions do not match. Unsure how to correct these issues. Pages 7 and 8 are the problems. Using mathcad prime 3.1

Hi, How can I evaluate these two limits in Mathcad15 where I show the steps?             Thanks in advance!

Hello, I am working on some Laplace Transform problems and the problem got messy quickly and I figured I would just use a given find to solve for A, B, C, and D(for the partial fraction). But I am unfortunately running into an issue that I have seen before but I cannot remember how I resolved it. The reoccuring issue is the last variable in the matrix will appear to be undefined when it is clearly defined beforehand. I want to make sure to write down how to properly use the given find so this issue will not occur again. Any help would be greatly appreciated.

Hi guys, in BS5628 there is a 'small area factor', this equates to "0.7+1.5A"A=areaI keep getting the error "these units are not compatible". I know its because 0.7 doesnt have any units, but the factor itself doesnt have units.Is there a way around this?

Hi ALL! Who is interested in the theory of wave-matter interaction opens mathcad blog.  It is a remake of a work done in the footsteps of a star of physics from the last century. Notes from lessons.  (Who knows the topic, please write a comment . Thank you - MF -   Physical Mathematics

Why an error in Mathcad 15? One simple ODE! I have converted in Prime 4 - no problems! See please pictures and sheets

Hello everyone,How is it possible that by changing the time of my ODE system, also the result change?I will link the program so that you can see what I am trying to say.  P.S. I use Mathcad Prime 3.1

Hi everyone, I have a problem using the vectors to solve this ODE system in Mathcad Prime 3.1. I know how to do it without the vectors, but it would be great if I could solve the system also using them. Is it possible or do I have to give up?

Hello I have been trying to open Mathcad 7 files on the trial version of mathcad 15 and everytime I get the message "Mathcad Application has stopped working". They are crucial files needed for my research so I would appreciate any suggestion on what to do.I have also tried converting to XMCD to view using Mathcad Prime 3.1 but always gives the message "Unexpected error encountered during conversion"

When setting up Prime Analysis in Creo 3.0, attempting to list Prime input/output returns the error "No properly tagged Prime variables found".Variables have been set up in a pre-existing *.mcdx file and the file loaded in the Prime Analysis set up dialogue in Creo. On the Input/Output tab of Prime, I select "Show As List" and all my variables are listed, yet the Input Selection panel in Creo remains dismally empty. Am I doing something wrong or is there a system or compatibility error?I'm also getting a "Quality Agent 3.0 F000 from PTC has stopped working" error at various times when using MathCAD and Creo.Quality Agent 2.0 F000 from PTC has stopped workingProblem signature: Problem Event Name: BEX64Application Name: qualityagent.exeApplication Version: 31.0.2012.380Application Timestamp: 53bc27cfFault Module Name: qualityagent.exeFault Module Version: 31.0.2012.380Fault Module Timestamp: 53bc27cfException Offset: 0000000000004acdException Code: c0000417Exception Data: 000000000000000

One hybrid Mathcad 15 sheet - one part with units and with a cloud function), one part without units! In Prime no problem but Prime has not animation! What can you say about it? Do you have more optimal solution?     Physical Mathematics  

Hi everyone, I am attempting to plot one column vector against another (one contains my x values and the other contains my intended y values). I embedded an excel sheet into mathcad and added units to the data. When trying to plot two vectors of the same length, I get "value must be real" error. There is nothing complex in my calculations. Im sure this is something simple, please help!Thanks,Chris

MCD15 has very nice plotting capability.  Plots can have a background grid so that values on the plots can be determined.  MCD Prime 4.0 plots do not have this feature which is annoying.

I have found an error in vector multiplication when the length of one vector is reduced to just one.  It should not throw an error, but does, stating that "These array dimensions do not match", which is just ridiculous.   Of course, there are workarounds, but this should be corrected.   Thoughts anyone?

I am new to Prime and have a basic question. I have a 2 page worksheet with the pages arranged left and right. When I print it out, I only get the left page and the footer says page 1 of 1. How do I get the right hand page to print?

Is it possible to produce subscripts or superscripts in text mode with prime 3.0 or 3.1 ?   if so how ?
