Linearization
Linearization is an approximation method.

Usage
A function f is given such that f(a) and f'(a) (i.e., the first derivative) are known, but f(x) for some x near a is not known. The linearization of f is used to approximate f(x) as:
This approximation method works in the multivariate case as well. Partial derivatives are usually notated like fx here. For example, for x near a and y near b...
