Comment #4 on issue 1304 by akshaysrinivasan: Integrate sqrt(x**2 + y**2) fails http://code.google.com/p/sympy/issues/detail?id=1304
Yes, but the problem is that M[b] which here is y**2 doesn't have the "is_positive" data descriptor. I'm still confused whether a symbol is assumed to be real by default or not. If it is assumed to be real by default, we can check if the parity of the exponent is even. But then, if its odd then we'll either have to assume y**n is positive and give the solution in terms of hyperbolic functions, or ask the user for more data - like maxima. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
