Question

if -1 + root3i = reitheta then theta =

Answer 1

Answer:

Step-by-step explanation:

So

theta in this case is the argument of the complex number -1+rt3 i

so in the 2d plane this complex number lies in second quadrant  

so theta is equal to pi- tan inverse 1/rt 3

which is pi-pi/6

which is equal to 5pi/6
