I am doing working a derivative of E
Can you tell me if I am doing it right.
chain rule:
SO, Y'=
for the second derivative, Y'', I use product rule, I believe.
product rule
Did I do it right?
Thanks you for replying. Perhaps you can further help me with this problem. The answer continues to evade me.I am trying to find the critical points of the equation. The book says to find the critical points, set f' = 0 .
According to mathlab, I should get critical points at x=-1 and x=1.
Unfortunately, I have been trying, unsuccessfully for hours, to see how Y' or
= 0 gives me a X=-1 and X=1
Can you help me?
