Q7 Q27.) Find zw. Leave your answer in polar form.
Question
Answer:
To multiply complex numbers in polar form: multiply the r parts and add the angle parts. Orr1(cos θ1 + i sin θ1) × r2(cos θ2 + i sin θ2)= r1r2(cos(θ1+θ2) + i sin(θ1+θ2))
so zw=3*8(cos(π/9+π/12) + i sin(π/9+π/12))=24(cos(7/36)π + i sin(7/35)π)
