Question

How do you convert `-3+4i` to polar form?

Answer 1

In polar form `Z= 5(cos 2.214+ i sin 2.214)`

Explanation:

`Z= -3 +4i` Modulas `(Z) = sqrt( -3^2+4^2) =5` Argument `(Z)=pi - tan^-1(4/3) =2.214`(radian) The point lies on the 2nd quaqdrant.
In polar form `Z= 5(cos 2.214+ i sin 2.214)` [Ans]
