Products and Quotients of Complex Numbers

11. Graphing Complex Numbers / Products and Quotients of Complex Numbers / Problem 2

Multiply the following complex numbers and express the final answer in polar form.
z₁ = 8(cos 59° + i sin 59°)
z₂ = 11(cos 91° + i sin 91°)

88(cos 150° + i sin 150°)

19(cos 150° + i sin 150°)

88(cos 328° + i sin 328°)

19(cos 328° + i sin 328°)

Multiply the following complex numbers and express the final answer in polar form.z1 = 8(cos 59° + i sin 59°)z2 = 11(cos 91° + i sin 91°)
