Z1 and Z2 are complex numbers, in their polar form. Compute the indicated mathematical operation and express your answer in Rectangular form. IMPORTANT NEW Note: Final answer requires 3 (three) decimal places, round up final answer if rule applies. Z1 = [r =|9| & theta = 120 deg] Z2 = [r =|7| & theta = 270 deg] Compute: Z1/Z2 = + *i

Solution

we can express compex no. as :Z1 = 9e^i(120) ; Z2 = 7e^i(270)

So, Z1/Z2 = 9e^i(120) /7e^i(270) = (9/7)e^i(-150)

(9/7)e^i(-150) = 1.28(cos(-150) -+isin(-150) = -1.11 - 0.64*i
