A particle moves along a line so that, at time t, its position is s(t) = 8sin2t. For what value of t does the particle change direction? The answer is t = (π/4) + πk and t = (3π/4) + πk for positive integers k how come the answer is not t = (π/4) + 2πk and t = (3π/4) + 2πk since that means one whole cycle? isn't π just 180 degrees?
