Question

express -2 - 2i in trigonoetric form

Answer 1

@majestymmm is 'i' an imaginary number?

Answer 2

Where is (-2,-2) on an x-y coordinate plane?

Answer 3

-2-2i
a+bi
magnitude,r =sqrt((-2)^2+(-2)^2) =2sqrt(2)
\[\theta=\pi +\tan ^{-1}(-2/-2)\] since a<0
=pi+pi/4
-5pi/4
Trigonometric form ,r =2sqrt(2)(cos5pi/4+isin5pi/4)
