1. ## Taylor Series Problem

Question:

Here is my attempt so far:

Note: I've used m where the question has used j.

My attempt is based off some bad notes I took in class so the way I am trying to solve the problem may not be the best. I'm struggling to work out how to continue from the part where I've left a question mark, and I'm not even sure if the Taylor expansion is correct.

Could anybody offer some thoughts as to what to do?

I think your Taylor expansion should look like $f(x_0+\Delta x) = f(x_0) + f'(x_0)\Delta x + ...$
