Question: Too many levels of recursion

Hi

Why Maple can't  calculate following definite double integral:

int(int(sin(x^2*y), x = 1 .. evalf(Pi)), y = 1 .. evalf(Pi))

Error, (in simpl/Re) too many levels of recursion

The approximated midpoint intgration gives the value -0.4552861717e-1

The Legendre root nodes with Christoffle weights gives the value -0.4552311444e-1

 

Thanks
