A 17-centimeter pendulum moves according to the equation π = 0.17 sin(5t), where π is the angular displacement from the vertical in radians and t is the time in seconds. Determine the maximum angular displacement πmax and the rate of change of π when t = 3 seconds. (Round your answers to three decimal places.)

The maximum angular displacement is 0.17 radians (about 10 degrees).
The rate of change
d(theta)/dt = 0.85*cos(5t);
when t = 3 seconds, this is -0.646 rad/s.
The rate of change
d(theta)/dt = 0.85*cos(5t);
when t = 3 seconds, this is -0.646 rad/s.
