Precalculus
Multiply the following complex numbers and express the final answer in polar form.
z1 = cos(π/5) + i sin(π/5)
z2 = cos(π/2) + i sin(π/2)
Divide the following complex numbers (z1/z2) and express the final answer in polar form.
z1 = 9[cos(5π/6) + i sin(5π/6)]
z2 = 45[cos(π/6) + i sin(π/6)]
z1 = 14(cos 65° + i sin 65°)
z2 = 7(cos 35° + i sin 35°)
