Unformatted text preview: b) Show that the sum of ALL these 6th roots is 0. 4) Let y = f(x) = x on the interval [0, 2]. Give the even extension of this function to the entire interval [-2, 2] and give this extensions infinite order Fourier series. Now use Parsevals identity on this even extension to show that 90 1 4 1 4 = = N N . 5) Use the Method of Steepest Descent to solve the system for its first quadrant solution (do one iteration) (x - 1)+ (y +1)= 25 and (x - 3)+ (y +2)= 36....
