Math: Complex Numbers?
Here is a question:
(a) Use de Moivre’s theorem to find the roots of the equation z^4 = 1 – i.
(b) Draw these roots on an Argand diagram.
(c) If z1 is the root in the first quadrant and z2 is the root in the second quadrant, find z2/ z1 in the form a + ib.
Can you please do this problem and explain how you do it???
What exactly do they mean by roots? i dont get it..
