The displacement (in centimeters ) of a particle moving back and forth along a straight line is given by the equation of motion x = 4isn pit + 4 cos pi t, where t is measured in seconds. (Round your answer to two decimal places). (a) find the average velocity during each time period. (b) Estimate the instantaneous velocity of the particle when t =1 .
