I was using Mathcad prime 3.1 to symbolically solve a pretty simple equation and I get imaginary numbers. While I was easily able to just do it by hand, I'm curious as to why it did what it did and how to stop it, if possible.
The solutions I've found posted here and elsewhere don't seem to help (i.e. using various assume commands)
File attached.
Thanks,
You probably know that Mathcads solution is perfectly correct - it sjust not presented the way we would call simplified. "Simplify" seems to be of no help here as Mathad/Prime/muPad has no preference for real results.
Playing around with that beast I found something curious - getting rid of the index in E makes Prime do what you want
It gets better!
Next I was playing with substitute, "E2=E" before "solve" and "substitute, E=E2" after solve and it worked OK, but then I found that using "substitute" on its own does the job as well. Don't ask for an explanation for all those effects!
BTW, while I experience a very similar effect in Mathcad 15 ever so often as well, I have no problems with your specific equation in this version:
