    Velocity formula from a position formula

    The position of an object, measured in feet east of a particular point, at time t, given in seconds, is given by: p(t)=2sin(t)-3cos(t). Correct to the nearest hundredth, what is the object's velocity at time t=-pi/4 seconds?

    In which direction is the object moving at time t=-pi/4 seconds? Assume that east is in the direction of the positive x-axis.

    Just take the derivative with respect to t and plug in the value of t you were given.
