z路w

Short Answer

Expert verified

The answer isz路w=6cos107掳+isin107掳

Step by step solution

01

Step 1. Given information

We have been given z=2cos85掳+isin85掳and localid="1646898828569" w=3cos22掳+isin22掳.

We have to perform the operationz路w

02

Step 2. Perform the operation

z路w=2cos85掳+isin85掳脳3cos22掳+isin22掳=6cos85掳+22掳+isin85掳+22掳=6cos107掳+isin107掳
