It is just how can you comment on the key features of the graph ?
Btw, i am doing an analysis task and there is a ques abt practical problem in creating an open cylinder with max volume. How do answer this ?
The Volume increases as the height increase. dV/dh = -(A^2)/ 4pih^2
We have an equation : V=(92pi-x)^2sqrt(4pix -x^2) )/ (24pi^2)
Sketch the graph of dV/dh and give comment on the key features of this graph
Sorry for giving unclear info ! Thx 4 ur time LOL
If you did, we might be a little further along in this problem. With 14 posts in this thread, I can't see that you have actually done anything.Do you know any rules of differentiation? The ones that would be very useful here are the constant multiple rule, product rule, chain rule, in that order. After you have found the derivative dV/dx, then you can graph it. When you have the graph, you can decide what you think are key features of it.
dV/dh = -(A^2)/ 4pih^2
V=(92pi-x)^2sqrt(4pix -x^2) )/ (24pi^2)
