How about. ds x B = (wkydx - 2khx^2/w^2)k should i sub in my equation for y in for y?

hmm actually, ds = dxi + dyj dy=-2hx/w2 * dx dx/dy=w2/-2hx dx= -w2/2hx *dy therefore, ds = (-w2/2hx*dy)i + (-2hx/w2*dx)j

I want to say di/dj = ds and so: y=h-hx2/w2 di/dj = dy/dx = -2hx/w2

I take the derivative of y with respect to x and voila?!

I'm not sure, I feel as if I need to express ds in such a way that it takes into account both the change in y and the change in x. Possibly a ratio?

hmm.. y=h(1-x2/w2) ??

This is what led me to believe that it was y=h-x2. Do you want me to say y=-ax2+h ? or am I completely approaching this incorrectly?

y=x2

Ouf, nevermind, x=w and y=h-w2 make sense to me now. I reviewed a little bit of my high school quadratic forms! :P

well in that case just y=h-w^2 but that doesn't make much sense to me, I was assuming something along the lines: y=-a(w+x)(w-x) ??

Yeah, isn't that what I have? y=h-x2

I'm sorry but I'm really not following. I guess I could find mass by using m=(density)(volume) but I'm still uncertain on how to express the volume of this object.
