Question

The displacement (in meters) of a particle moving in a straight line is given by the equation of motion s = 1/(t^2), where t is measured in seconds. Find the velocity of the particle at times t=a, t=1, t=2, and t=3.

Answer 1

Is it possible to use lim h->0 [f(a+h)-f(a)] / h, to find the derivative? I've heard it's very tedious, leading me to believe it is possible, but I always end up with the limit does not exist

Answer 2

Thanks
