Hello, I'm having a problem solving a Given Find cycle with vectors. I'm trying to plot T vs. X1 and T vs. Y1. Mathcad gives me back always the same value for Y1 and incorrect values for T. Using minerr I don't get better results. Can someone tell me what I'm doing wrong?

The hard drive in my new laptop where mathcad prime 3.1 was installed was crashed.The computer will be replaced with a new one soon.Once I get it, how can I re-install the software?

You can down load sheets (MC 15 and Prime 3) of the Euler Method of ODEs solution.One question - how simple have arguments of the augment function - as in rkfixed (see the plot please)?Must be one form for this arguments for one ODE and 2, 3, 4... ODES.

I used to use full version MATHCAD. By using "Select All" and "Copy Selection", I can copy the data from my mathcad worksheet, and paste it to Excel directly. Recently I am using a trail version in a Windows 8 system. When I tried to do the same thing, by selecting some data and click "Copy selection", it shows a bitmap or some other kind of figure will be pasted to the excel, instead of the data itself. I do not know what happened, and just want to copy the vectors of data. Would anybody know how can I solve this problem? Or is it a restriction of trial version? Thank you!

Hello. Does anybody know what is the limit number of equations in the given-find block? I use version 15 of Mathcad.Piotr

Have not used MathCad 7 for several years.Cannot remember how to display the various Palettes available.Call myself Dinosaur because I once used slide rules, not because I am a multi-ton reptile-like creature.

Does anyone know how to plot something like the equation in the attachment in mathcad?

I have just moved my mathcad 14 software to my new laptop and wanted to check to see if there were any updates for it. How do I do this?ThanksJohn

Hi, i suppose my problem has a easy solution, but I cant find it.I define a simple operation k(B), I got the results but by some circunstance I got a solution that I need to change, so I want to create a new matrix with the modified results and call it back to use it on an equation but I wrong results... (image attached)..As you can see in the image, when I select the new matrix, I can not change the Math Properties (Tab).Hope you can help me.

Hi,I'm using the given - find solve a series of equations and the number of variable that are being solved for has resulted in the find statement being longer than the page width, is there a simply way to get this onto one page width, ie on a second line etc. before I start to look at changing the variable names or possibly carrying out some substitution in the equations to reduce the number of solve variable's. I'm Using Mathcad 15. Thanks.

Hello,I'm very beginner. I'm trying to solve ode with boundary conditions (see the attached)I have an error in the unit of second b.c. (n'(10 um) = 0 cm-4).Please help me to solve this problem. Thank you in advance.

Hì, I have serious problem with using Mathcad 15 M010 under win7 64bit. I'm not able to insert a 3D graphs and get error message when I use qsheets the error message is (failed to lunch application server). Please help me to resolve this issue.Thanks Nader

Hello, I am trying to split the input current for a buck in 2 or 3 ranges depending on the output power, but I cant get the plot right. I am using mathcad 15.0.

Let's say I define a vector variable and then I want to do sigma summation for every element, from 1 to the element. Can I do this? Or perhaps with a range variable?ThanksJoe

Hi,I made a separate Math CAD sheet where I have wrote a function Now I am trying to insert this sheet into my main calculation sheet as Insert--------> ReferenceSo that I can recall that functionBut it is not working.Any ideas!BR,J.Randeep

HiI couldn't understand why the function with condition statement in this case IF statement as shown below dose not work properlyIs this right way ? or I am making some mistake.BR,J.Randeep

Why we have double vertical line in programs?I think inaf is one! One black (left) and one gray (rait).Compare pleaseSubquestion!Why we have in English the word enough?I think inaf is enough!

Please excuse my ignorance, but I am really in a bind. I am not a Mathcad wiz, but I need to use it for a graduate class. I have a Mathcad sheet I have started, but I cannot figure out for the life of me how to get the final units in the proper format (ft).I am using the given/find solve block. I have defined all variables prior to the solve block. Spreadsheet is attached.

Hi, is it possible to change row in a equation in mathcad so that it fits in one a4 page?Like this:I=b*h^3/12+b*h*(x-xtp)^2+... ...Bw*tw^3+etcI have equations that is longer then one page can fit.Thanks!

Often data plotted or functions have end uses which showing acceptable range is importand. Older versions allowed entering a constant function among the traces. Mathcad 14 doesn't seem to do this. How does one accomplish the function?

I note that in Mathcad 15 there is Reference Information given. I'm worried that for an exam that I will forget some of the formulas such as :cos(A+B)=cosACosB-sinAsinB - does anyone know if such formulae are buried in the depths of Mathcad anywhere ? Or does Mathcad not go that far to expand such things for us ?thanks,
