I'm doing my homework and i keep getting a positive angle, but the answer is saying the angle is negative. why is this negative?
(3-i)^6
r=square root of 10
a=r cos alpha
alpha=3/square root of 10
alpha=18.43494882
I have done this and similar problems over and over and can't figure out how they get alpha= -18.43493882
