> 1. You have a variable x and a function x. Are they related?
Yes, they are supposed to represent the same thing.
> 2. I think that you should use assignment, not function definition.
I guess I was trying to make this too difficult. Thanks for tip, should have been a no-brainer.
b : x / cos(t);
y : sqrt(b^2-x^2);
x^-2 + y^-2 = 4;
Works great, and is much simpler than the function version.
> 3. Solve does not consider any information given with assume.
Interesting, I had assumed it would (no pun intended). It makes me wonder if I could make a script that would check the results of solve, and return only the valid answers. But this could easily grow to be more complex than I would like to handle.
I appreciate the help.
