New issue 1275 by ffxvzero: tsolve errors on exponentials
http://code.google.com/p/sympy/issues/detail?id=1275
sympy fails to solve this equation:
x = sympy.Symbol('x')
tsolve(1.0 + 2.0*x + 3.0*sqrt(1-x**2),cj3)
(solve errors saying that it is not a valid polynomial, hence I'm using
tsolve)
i'm attaching a patch to solvers.py (against sympy 01/25/09) that makes it
possible to solve this. This includes two changes:
- handling the case when lhs.is_Pow is True
- modifying the is_Add statement to treat terms with powers in them as
functions. If a function is with a power, it will call tsolve once more
rather than solve. This is probably a hack, but it works for my purposes
