Hi all well basically i have finished off chain rule and right now i am going through product rule and quotient, as i was going through some questions , i understood the basic rule and so on, but why i dont get is, how do i figure which rule i need to apply given equation using these three rules. For instance : y= x^3 sinx or y=x^3 / sinx , why would it be wrong to apply chain rule? Thanks for your replies ;) (grr i gotta figure out using Latex =/)
