## Homework Statement

Find the first three non-zero terms of the Taylor expansion about zero in each of the following cases:

a) (1+2x)^-1/4

b) sin(x^2)/x

**2. The attempt at a solution**

I don't even know where to begin. I've only just read about what Talyors expansion is, and I don't know what's meant by 'about zero'. If someone could show me some answers and the steps they took to arrive at them though, I'm sure I would learn a lot from it.
