Question
In the problems below, assume all closed contours are traversed in the
positive (i.e. counter-clockwise) direction.
1.) Consider the function
2ez
f(R) = f√ √ = R 22 + 3 dz
|2|=R
where R≥ 0 gives the radius of the circle centered at the origin over
which the function is being integrated. Determine the value of the
integral for all values of R where it is well-defined. If the integral is
likely to diverge for some value of R, explain why.
