Answer:
(2, 120° )
Step-by-step explanation:
To convert from rectangular to polar form, that is
(x, y) → (r, Θ ), use
r =
Θ = ( )
here (x, y ) = (- 1, )
r = )^2
= = = 2
Θ = () = 60° ← related acute angle
Note (- 1, ) is in the second quadrant so Θ must be in the second quadrant.
Θ = 180° - 60° = 120°
(- 1, ) → (2, 120°)

Answer:
Step-by-step explanation:
The polar form of a Cartesian coordinates is given by (r, @) where r = √x^2 + y^2
@ = tan^-1 y/x
r = √-1^2 + √3^2
r = √4
r= 2
@ = tan ^-1 √3/-1 -tan √3/1 = -60°
@ = 180-60 = 120°
