# Math Help - Taylor series expansion (simple)

1. ## Taylor series expansion (simple)

Need to linearize the following functions using the Taylor method with 1 as the point of expansion:

A) U = ln(c)
B) U = 1 - e^(-c/2)
C) U = c^(1/2)

By linearlize do you just mean $f(1)+f'(1)(x-1)$?

3. All I know is that we're supposed to use something like this:

It doesn't look too difficult and I did get some solutions out but I have no idea if I'm actually on the right track.
