Point P is located at the intersection of the unit circle and the terminal side of angle theta in standard position. Find the coordinates of P to the nearest thousandth.

Question

theta = -105degrees

Please explain the steps. I'm completely stuck.

Answer 1

Θ is 105º clockwise from the x-axis

this gives a 75º reference angle with the negative x-axis

the x and y coordinates are both negative

x = - cos(75º)

y = - sin(75º)
