New issue 2079 by asmeurer: multiple integral gives wrong result
http://code.google.com/p/sympy/issues/detail?id=2079
In [84]: Integral(sin(x*y*z), (x, 0, pi), (y, 0, pi), (z, 0, pi)).doit()
Out[84]:
π
⌠
⎮ ⎛ cos(π⋅y⋅z) 1 ⎞
⎮ ⎜- ────────── + ───⎟ dx
⎮ ⎝ y⋅z y⋅z⎠
⌡
0
But obviously, the integrand shouldn't have y or z in it if it has already
integrated with respect to that.
