Question

Enter the coordinates of the point on the unit circle at the given angle. 120°

Answer 1

The coordinate is (-1/2, √3/2) and the missing values will be 2 and 3 if the angle is 120 degree.

What is the polar equation?

A polar coordinate system is a two-dimensional coordinate system in which a distance from a reference point and an angle from a reference direction identify each point on a plane.

We have an angle of 120 degree

θ = 120 degree

r = 1 unit

As we know, the coordinate in the polar form from the rectangular form is:

x = rcosθ = cos120 = -1/2

y = rsinθ = sin120 = √3/2

Thus, the coordinate is (-1/2, √3/2) and the missing values will be 2 and 3 if the angle is 120 degree.
