I'm having trouble getting the answer to this particular question out;
Given that the is equal to ;
- Find y if there is a stationary point at
- Show that
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
