The displacement (in centimeters) of a particle moving back and forth along a straight line is given by the equation of motion s= 3 sin(?t) + 4 cos(?t), where t is measured in seconds.(Round your answers to two decimal places.)(a) Find the average velocity during each time period.[1, 2][1, 1.1][1, 1.01][1, 1.001](b) Estimate the instantaneous velocity of the particle when t = 1.
