Algebra 2: Coordinates on the Unit Circle
Use the unit circle to give the exact coordinates (cos θ, sin θ) of the terminal point for each angle. The reference circle above shows every special angle.
- 1.Find the coordinates (cos θ, sin θ) of the point on the unit circle at θ = 150°.
- 2.Find the coordinates (cos θ, sin θ) of the point on the unit circle at θ = 0 rad.
- 3.Find the coordinates (cos θ, sin θ) of the point on the unit circle at θ = 180°.
- 4.Find the coordinates (cos θ, sin θ) of the point on the unit circle at θ = 5π/3 rad.
- 5.Find the coordinates (cos θ, sin θ) of the point on the unit circle at θ = 315°.
- 6.Find the coordinates (cos θ, sin θ) of the point on the unit circle at θ = 3π/2 rad.
- 7.Find the coordinates (cos θ, sin θ) of the point on the unit circle at θ = 225°.
- 8.Find the coordinates (cos θ, sin θ) of the point on the unit circle at θ = π/6 rad.
- 9.Find the coordinates (cos θ, sin θ) of the point on the unit circle at θ = 120°.
- 10.Find the coordinates (cos θ, sin θ) of the point on the unit circle at θ = 4π/3 rad.
