is a differntial equation...here is what you do...since ......ok now seperate to get then integrate to get ...now stop before we get to y we must find that c...we know there is a stationary point at c which means the slope is 0 at which means that y'=0...so thefore solve and you see c=0...next integrate again to get y and you see that now using that condition again we know that solving we get x=0..therfore

for part two just add nine times what we just found to what is to verify its zero - Apr 7th 2008, 09:11 PMFlay
Got it. I was making yet another stupid mistake.
