I came across this proof in my notes and I could use some help getting started.
Let . Then, prove that is differentiable at any point and .
I know how to prove ones that are simpler such as but this one is a bit harder for me to figure out.

Thank you for your answer. However, this is much different notation then what my professor uses in class. I will show you the proof that he gave for a simpler problem and then maybe we can modify your solution to fit his notation...

Proof:
as .
