Question

Find the point (2, y) om the circle of radius 2 that corresponds to the angle1176

Answer 1

Given the angle:

`(11\pi)/(6)`

The sine function: sin θ = y/r; then:

y = r sin θ

y = 2 x sin 330°

y = -1

Now for x, we have:

The cosine function: cos θ = x/r; then:

x = r cos θ

x = 2 x cos 330°

x = √3

Point: ( -1, √3)
