Operations of Complex Numbers in Polar Form 1. Find the product of z1 = 2/3 (cos60° + i sin60°) and z2 = 9 (cos20° + i sin20°) where 0 ≤ theta ≤ 360°

2. Given z1 = 12 (cos pi/3 + i sin pi/3) and z2 = 3 (cos 5pi/6 + i sin 5pi/6), find z1/z2 where 0 ≤ theta ≤ 2pi

3. Find the quotient of z1 = cos 2pi/3 + i sin 2pi/3 and z2 = 2 (cos pi/12 + i sin pi/12) where 0 ≤ theta ≤ 2pi
