Homework Statement
Use polar coordinates to change the following double integral to a single integral involving only the variable r.
Double-Integral( [tex]\sqrt{1+(x^{2}+y^{2})^{2}[/tex] )
The x-y region is x^2 + y^2 = 4 in the first quadrant.
2. The attempt at a solution
I got upto this:
Integral(pi/2 sqrt.(1+r^4) r dr)
Did I do it right?
