That's all correct so far (as far as I can see) now just find dA/dT in terms of A only.(Original post by katerobertsonxx)
I have had a go and I am even more confused now as I have no K anywhere,
I have written down:
dV/dX= 3x squared
dA/dT= da/dX x dX/dV x dV/dT
= 12x x 1/3x squared x 1/2 V to the power 1/3?
am I completely going the wrong way?
And actually passed?
