Hhmparticle9 replied to the thread Undergrad Proving that convexity implies second order derivative being positive.We can say $$f'(b) < f'(b+\epsilon) < f'(b+2\epsilon) < ... < f'(c)$$ for some ##b < c##.

Hhmparticle9 replied to the thread Undergrad Proving that convexity implies second order derivative being positive.I think I understand where you are coming from now. If we let ##a## tend to ##b## then since ##c## is in ##(b,a)## we must have ##f'(b)...

Hhmparticle9 replied to the thread Undergrad Proving that convexity implies second order derivative being positive.I just realized that my proof is even more wrong. I need to show that ##f'(x) > f'(y)## for ##x > y##. Sorry guys. I am well off.

Hhmparticle9 posted the thread Undergrad Proving that convexity implies second order derivative being positive in Calculus.There are probably loads of proofs of this online, but I do not want to cheat. Here is my attempt: Convexity says that $$f(\lambda a +...
