A point starts at the location (2, 7) and moves counterclockwise along a circular path that is centered at (0, 0). The point moves at a constant speed. Imagine an angle θ with vertex at (0, 0), subtending the object's path. The angle sweeps out θ radians per second, and let t represent the varying number of seconds that have elapsed since the point started moving (Draw diagram to represent this). Write a formula that expresses the y-coordinate of the point in terms of t. (Hint: Start by expressing the angle measure in terms of t)
