FAQ
Q: What is a unit circle?
A: A unit circle is a circle with a radius of 1 unit.
Q: What is the purpose of a unit circle?
A: The unit circle is used in trigonometry to relate the angles to the coordinates on the circle.
Q: How do you find the coordinates of a point on the unit circle?
A: The coordinates of a point on the unit circle are (cosine(angle), sine(angle)).
Q: What are the special angles on the unit circle?
A: The special angles on the unit circle are 0°, 30°, 45°, 60°, and 90°.
Q: What are the values of sine and cosine for the special angles on the unit circle?
A: For 0°, cosine = 1 and sine = 0; for 30°, cosine = √3/2 and sine = 1/2; for 45°, cosine = √2/2 and sine = √2/2; for 60°, cosine = 1/2 and sine = √3/2; for 90°, cosine = 0 and sine = 1.
