Best ResponseYou've already chosen the best response.0I think the answer is 3(cos 90° + i sin 90°) but I just need confirmation from someone cause I'm not 100% sure. :)

Best ResponseYou've already chosen the best response.1Hmm so we're moving along the Imaginary axis, in the negative direction, 3 units. So I think we're moving straight DOWN 3 units. So our angle would need to be \(90^o\) or \(270^o\) :o
