Helping solving this problem symbolically in Prime 3.0

I need to solve this in terms of r. I clearly am missing something basic. Any help would be greatly appreciated.

Solve what?

BTW, if you define a1(r):=... and then e(r):=... you have to write a1(r) etc. on the RHS of the assignment, too. This applies to all of your function definitions.

Thank you for the help. That was the piece I was missing.

To answer your question, I was trying to solve for the delta-V for the hohmann transfer in terms of r.

I ended up solving in terms of r, Re, and mu.

I attached the updated document, if anyone is interested.

Fine, so I answered the question without being aware of.

I wouldn't call it solving what you do in the sheet, though. If you have x+1=3 and you are searching x, thats what I would call solving. Therefore the quertion of mine.

BTW, the definition of a2 is still missing the arguments on the RHS, but its never used anyway.
