You're correct Nath, it

*first*comes to rest(assuming it's moving along the positive x-axis) at

Left of the y-axis, it first comes to rest at

Add or subtract multiples of to arrive at any subsequent extrema. The corresponding y values are -2 or 2. - Jul 10th 2006, 06:55 PMmalaygoelQuote:

It's easy to overlook the little things. Anyone who has done math knows that.

I do it all the time.
