Mathcad

Hello,in this calculation, the result should be 't1' (as you can see easily): Why doesn't Mathcad Prime 3.1 simplify this term correctly?Many thanks for any answer.Best regards, J. Dessecker

Hello,i have a sheet with at this time five pages (thats the beginning...). There are two Pictures on page 1. Since i have calculated two very complex vectors from IR^3 (at page 5), the regions in the whole sheet move without any action. This is very, very annoying. How can i prevent this?Best regards and mnay thanks for any answer, J. Dessecker

I want to see the values of f(n) by using the find command.But i am getting the error as variable is undefined.Please help me.Thanks in advance

Dear PTC Community Users.   I attached a simple file about Distributed Forces (Beams - Internal Effect). The force V is called the shear force and the couple M is called the bending moment. Theseeffects represent the vector components of the resultant of the forces acting on a transverse section of the beam.Regards   SBL

Hello there,Has been a long time since I use prime, but there is some shortcuts that Idon't know how to do it:Equals to, like CTL + =Its like impossibrl becouse o use = on my PC its SHIFT + 0, and I try CTL+SHIFT+0 and CTL+0, what i'm doing wrong?One more thing, I have a fractions like 2/(2s+8), how can I choose numerator or denominator?regards,LL

A professor of physics at the MEI told me the following story, or rather told of such a trend. After the lab, students should in the same laboratory hooked to a computer, open a settlement site on the Internet, enter it on the stand received the experimental data, process them and the least squares method to obtain the desired functionality and graphics depending on the evaluation of errors....So, more and more students do not sit down to the computer and take out their smartphones, go through them to the correct site and enter the initial data, working (and quite cleverly) ... thumbs of both hands. On the question of why they do not use computers, these students say that they have almost forgotten how to work with a normal computer keyboard. And you say - Mathcad.PTC!Where is Mathcad for smartphones, tablets etc?

Hello all,Am trying to present my data in a box plot:Is it possible to add a label to each of my boxes? Ideally under the X axis inline but anywhere on the graph would be fine. Looking at how it generates the plot I would think not but doesn't hurt to ask.I would also like to change the y axis to a log scale but it's complaining that I have a non positive value in my dataset? Clearly from the data this shouldn't be the case.Lastly is it possible to look into the code behind the "boxplotgraph()" function, and modify it to do something different?

Hello,I am thinking to update my mathcad 15 to mathcad prime 3.0 and I was wondering if prime 3.0 has automatic content like microsoft office. Please has anybody prime 3.0 and know to say me if it has smth like this?Thank you

Hello,I was learning the Thomas algorithm and I got stuck at a point where it says "This array index is invalid for this this array"; I check the system but I couldn't find such a problem causing anywhere. I attached the mathcad code; any assistance will be appreciated

I have tested in Mathcad Prime 4 the MCDX to XMCD converterand have find one bug - see please the Mathcad 15 file

Fitzhugh-Nagumo Equation

Is possible to save a Mathcad 15 worksheet with all the plots so as to avoid the need for recalculating all the plots when the file is reopened

I recently purchased mathcad prime 3.0 and was wondering how to define the units on the independent variable of a function with out defining a specific number for the variable. For example,if I had the function f(x)=x^2, and I wanted x to be in seconds, how would I tell that to mathcad?Thanks

Hello,i am trying to plot this surface, but it is not showing. not sure what i am doing wrong. Thank you!

hiI want convert a file of mathcad15 to prime , but i have not mathcad15 in my pc and i couldn't instal mathcad15 in my pc .How can i see the program ?can someone convert this program to prime for me ?

Is below too simple for Mathcad? I'm using Prime 2.0. What am I doing wrong? Kind regards,Michael

I am trying to create an interaction diagram for a circular concrete column. This is based off of an Excel spreadsheet that is currently being used and I am trying to convert that into a Mathcad spreadsheet. in the Excel spreadsheet the vertical load strenght and moment strength were found using the what-if function. The Excel spreadsheet solves for the total vertical load strength by adding the vertical load strength of the concrete (Pconc) and the vertical load strength of the steel (Pst) as is the same for the total moment Mn = Mconc + Mst. for Pst and Mst I am using the Range of Variable Summation to sum the values in a Range (obviously). The summation comes up with the right value, but I need this to be converted back into a range as it is dependent on the value c. That is pretty confusing so I will give an example. c is a range of values. the first value of c is 0 which gives me a sum(Mst) = 8.05 * 15^-15 but I need the sum(Mst) to change as c changes because It needs to be added

This is a lecture in Optimization given to a group of Mechanical Engineers, which was coducted by me, upon a request to demonstrate Mathcad Prime 2.0 in solving Optimization.From the example given (Particle Swarm Optimization), it shows how simple to optimize the problem once the mathematical Model is formulated correctly.Though I am not a Mechanical Engineer but I do have a very good mathematical background. The results were remarkable with that given in the article and really it shows how powerful Mathcad Prime 2.0 is.

Dear colleagues, I`m not so experienced user and encountered with some problems with curve fitting functions (Genfit works but LeastSquaresFit does not - gives the error that data units are not compatible). Could you help if possible? I`m completely stucked. Thank you.
