Comment #1 on issue 1393 by fredrik.johansson: integrate(x**2 * sqrt(5-x**2), x) can't do it yet http://code.google.com/p/sympy/issues/detail?id=1393
Let's add pattern matching to handle integrals of types such as P(x)*sqrt(Q(x)), P(x)/sqrt(Q(x)), sqrt(Q(x))/P(x), etc. This should be worthwhile even if the Risch integrator is fixed to handle them some time in the future, because 1) it shouldn't be much work, 2) the code should run faster (and these integrals are common), 3) we might get slightly prettier output (e.g. with inverse trig functions instead of complex logarithms, etc). -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
