A point starts at a location on the r-axis and travels CCW around a circle that is centered at (0, 0) at a constant angular speed. The function f(t) = 22 . sin(4t) gives the point's y-coordinate in terms of the number of seconds t since the point started moving. For each quantity below, determine which expression represents that quantity's value. . The period of the graph of f. a. 4 - v The radius of the circle that the point moves along. b. 4 v How long it takes the point to complete one full lap around the circle. c. 22 The amplitude of the graph of f. d. 4t How many radians the point has swept out t seconds after it started moving. e. sin(4t) How many radians the point sweeps out per second
