Integral problem "reverse order"
Greetings,
This is from an online homework question:
Evaluate the integral by reversing the order of integration.
[tex]\int^{1}_{0}\int^{8}_{8y} e^{x^{2}}dxdy[/tex]
Although, I fail to see how this works, if I switch the order I get:
[tex]\int^{8}_{8y}\int^{1}_{0} e^{x^{2}}dydx[/tex]
after integrating wrt y, it boils down to
[tex]\int^{8}_{8y} e^{x^{2}}dy[/tex]
which won't give me a number... did I do something wrong?
