Maple evalf(int) doesn't work for me

evalf(int(Pi^2*exp(-N(cos(phi)+sin(phi))), [N = .1 .. 100, phi = .1 .. (1/2)*Pi]))

This result is basically the same expression. It doesn't seem to be trying to calculate it. What am I doing wrong?

You need a multiplication sign after the N. A name immediately followed by a left parenthesis is viewed as function application, not multiplication.

Also, if you know that you want numeric integration rather than symbolic, you should use Int rather than int. Otherwise it wastes time trying symbolic integration in vain.
