Question

-1+i corvert each of the complex number plar form​

Answer 1

$let \: \: \: z = - 1 + i \\ |z| = r = \sqrt{2} \\ \\ \theta = {tan}^{ - 1} | - 1| \\ = \frac{\pi}{4} \\ \\since \: the \: poine \: lie \: in \: second \: quadrent\\ amp( z) = \pi - \theta \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \pi - \frac{\pi}{4} \\ \: \: \: \: \: \: \: \: \: \: \: = \frac{3\pi}{4} \\ polar \: form \: is \\ \sqrt{2} ( \cos \frac{3\pi}{4} + i\sin \frac{3\pi}{4} )$
