1 If a particle's position is given by x(t) = 7sin(3t-π/6), what is the velocity?

	v(t) = 21sin(3t-π/6)
	v(t) = 7cos(3t-π/6)
	v(t) = 21cos(3t-π/6)
	v(t) = -21sin(3t-π/6)
	v(t) = -21cos(3t-π/6)

	a(t) = -63sin(3t-π/6)
	a(t) = +63sin(3t-π/6)
	a(t) = -21cos(3t-π/6)
	a(t) = -21sin(3t-π/6)
	a(t) = +21sin(3t-π/6)
