Symbolically Solve Simultaneous Equations in Mathcad P3.0

Hello,

I'm trying to solve simultaneous equations in MathCad Prime 3.0, but all I get back from find(x,y)--> is find(x,y). Is this a feature that is planning on being implemented or has been and I'm not aware of the correct syntax. I know from the forums that it was not in 2.0. http://communities.ptc.com/thread/39577

This is a new "feature" of Prime that solve blocks cannot be evaluated symbolically anymore like we were used from Mathcad 15 and below. I am not aware that its on PTCs todo list for future versions.

Maybe you are able to use use the symbolic "solve" to do the job.

BTW, did you had success already with your waterfall plot? http://communities.ptc.com/message/230804#230804

This is rather unfortunate to hear. I suppose I will start to learn M15 instead of using prime. Although I like the way Prime's interface is and the ease of use with formatting and how it is displayed, it just isn't worth it if many of the features haven't been reimplemented.

I just got used to almost learning all of the keyboard shortcuts for MP 3.0.

You can't do a solve block; but you can still solve symbolically

Thank you Fred. That worked out quite well for my problem.

FYI; I have a rod with internal heat generation on one half, but I'm keeping the convective term in the solution, thus I have a Linear 2nd Order Non-Homo DEQ. I was needing an analytical expression for the temperature, and was having trouble with the constants.
