Question

Y

(0.1)
Find the coordinates of the point (x, y)
shown on the unit circle.
X=?
Y=?

Answer 1

Answer: x= -1/2 y= -root3/2

Explanation:

Answer 2

the coordinates of the point of x and y is -1÷ 2 and -√3÷ 2

Explanation:

The computation of the coordinates of the point is shown below:

The angle is

= 4π ÷ 3

The radius is 1 unit

Now

x = rcos
`\theta`, and y = rsin
`\theta`

Now

x = 1cos(4π ÷ 3) = -1÷ 2

y = 1sin(4π ÷ 3) = -√3÷ 2

hence, the corordinates of the point of x and y is -1÷ 2 and -√3÷ 2
