Perform the indicated operation:
a) express the answer in rectangular form:
[5(cos103 degrees + jsin 103 degrees)]
Forms:
x = rcos(theta); y = rsin(theta)
x = 5cos(103) = -1.12475 ; y = 5sin(103) = 4.87185
Ans: -1.12475 + 4.87185i
=======================================================
b) express the answer in polar form:
(16.le ^2.03j)(11.9e^-3.34j) I got 192angle-1.31?
Correct
=======================================================
c) express answer in rectangular form:
(3angle264 degrees)(4angle72 degrees) I got 10.96-4.88j ?
Follow the example in "a".
================================
