Question 1009712: Can I have some assistance on this problem?
A particle moves along the number line so that it's directed distance from the origin at any given time t is given by s(t) = -2 sin t
Find the velocity(the rate of change of s) of the particle at t = pi seconds.

A particle moves along the number line so that it's directed distance from the origin at any given time t is given by s(t) = -2 sin t
Find the velocity(the rate of change of s) of the particle at t = pi seconds.
-------
v(t) = s'(t) = -2cos(t)
v(pi) = -2cos(pi) = -2 units/second
