Evaluate over the x,y plane:
And I know the answer SHOULD be [itex]\pi[/itex]
Polar-->rectangular identities maybe?
x--> rcos, y--> rsinθ, dxdy--> rdrdθ
The Attempt at a Solution
I tried using polar coordinates, but it doesn't simplify to something nice. When I did I got:
But there isn't an identity that simplifies the exponent into something easier to handle
