Q1. Determine the missing coordinate and given the quadrant in which the point is located:
(−1/( 8 ), y)
Q2. Verify that the point (−1/( 8 ),−(3√7)/8) lies on the graph of the unit circle. Then use symmetry to find three other points that also lie on the unit circle.
Q3. If ((−1)/4,√15/4) is a point on the unit circle corresponding to a real number t, find the values of the six trigonometric functions of t.
