A particle moves on the xaxis so that its velocity at any time t is given by v(t) = sin 2t. At t = 0, the particle is at the origin.
a)For 0 ≤ t ≤ π, find all values of t for which the particle is moving to the left.
b)Write an expression for the position of the particle at any time t.
c)For 0 ≤ t ≤ π/2, find the average value of the position function determined in part b.
