recall dA = rdrdtheta
so you have re^r^2) which can be integrated with a simple substituion
Let D be the disk of radius 6 centered at the origin. Find the
double integral of the function f (x, y) = e^(x^2 +y^2) over D
When I do this i get a function that says e^r^2, and then I'm uncertain as to how to integrate this, I don't think I'm using polar co-ordinates correctly. Any suggestions/ideas?
Thanks for your reply, I think I was quite unclear in my question though, my problem lay with integrating a function that was e^u,(integrating the substitution), and when I tried to carry out the second integral, it did not have any variables with theta hence, I was unsure how to proceed...
