. Let C1 be the circle z| = 7 in Let f (z) = the counter-clockwise direction, C2 the circle z - 8 = 7 in the counter-clockwise direction, and finally C3 the square with vertices (7,7), (-7,7),(–7, –7) and (7, –7) in the counter-clockwise direction. Part (a) 1 What is 2ni 2ri J. f(2) dz? C1 Part (b) 1 What is 2ni | f(2) dz? C2 Part (c) What is 2ri Je f(2) dz? C3
