Hey, stuck on this question, have managed to do the others in the exercise which are based around arguments of 180° and 90° but cant figure how to do these... probs tryin so hard that ive missed a really easy solution....
Express these vectors in the a + ib form;
modulus 12
argument 2π/3
modulus 4
argument -π/3
The answers are : -6 + 6√3i and 2 - 2√3i
Thanks in advance,
