The Unit Circle Answers

Find the coordinates of the point (x, y) shown on the unit circle. x = ⇒ -1/2?

The angles that share the same sine value as sin(45°) have terminal sides in quadrant IIIIIIV(none of the quadrants).

The angles that share the same tangent value as tan(45°) have terminal sides in quadrant IIIIIIV(none of the quadrants).

When theta = negative 210 degrees, phi = degrees.

Consider all angles whose reference angle is 45° with terminal sides not in Quadrant I.The angles that share the same cosine value as cos 45° have terminal sides in quadrant IIIIIIV(none of the quadrants).
