4. (15 points) Evaluate the line integral fC(22:3 y3)da: + ($3 + y3)dy where C is the unit circle. This integrals will be evaluated in two different ways, and both results should match. 0 Parametrize C and substitute to evaluate the integral 0 Use Green's theorem to evaluate the integral IMPORTANT NOTE: In the first case, the resulting integral will be very tedious to perform. Once you've completely simplified the integrand, you may evaluate the integral using the mathematical tool of your choice. For the second case, once you've changed the line integral to a double integral using Green's theorem, convert to polar coordinates and the integral should be easier to perform
