(a) If t = -, determine the quadrant in which the unit circle point P(t) lies. 3 Quadrant I Quadrant II Quadrant III Quadrant IV It lies on the x-axis or y-axis (between quadrants) (b) If s= -11T 5 find a real number t in the interval [0, 2) such that P(t) = P(s). (Recall that P(t) and P(s) represent points on the unit circle.)
