answered True or False: If $f$ is differentiable at $a$ and $g$ is differentiable at $f(a)$, then $(g\circ f)''(a)=g'(f(a))f''(a)+g''(f(a))(f'(a))^2$

I also do not understand how you came to this answer.

@AndréNicolas, Do you mean that distinguishable as in Dice1, dice2 and dice3? Organized counting would be the order we add them?

comment Show that $\int_{x=a}^{x=b} f'(x) g(x) dx=f(b)g(b)-f(a)g(a)-\int_{x=a}^{x=b} g'(x)f(x)\, dx$
why do you have $x=a$ and $x=b$ for the limits of the integral? I just haven't seen that notation before and wondering why and in which branch or location in the world it is used.
