Find the quotient of

9 (cos 135 + i sin 135)
-
7(cos 10 + i sin 10)

picture is a bit clearer

b

Step-by-step explanation:

cos(t) + i * sin(t) = e^(i * t)

Therefore, (cos(t) + i * sin(t)) / (cos(s) + i * sin(s)) = cos(t - s) + i * sin(t - s)

9 * (cos(135) + i * sin(135)) / (7 * (cos(10) + i * sin(10))) =>

(9/7) * (cos(135 - 10) + i * sin(135 - 10)) =>

(9/7) * (cos(125) + i * sin(125))
