Linear approximation - Wikipedia, the free encyclopedia
In mathematics, a linear approximation is an approximation of a general function using a linear function (more precisely, an affine function). They are widely used in the method of finite difference...

This approximation is crucial to many known numerical techniques such as Euler's Method to approximate solutions to ordinary differential equations. The idea to use linear approximations rests in the closeness of the tangent line to the graph of the function around ... Exercise 1. Use linear approximation to approximate ;

From this graph we can see that near  the tangent line and the function have nearly the same graph.  On occasion we will use the tangent line, , as an approximation to the function, , near .  In these cases we call the tangent line the linear approximation to the function at .

The Fig. 4.1 shows you what the linear approximation is doing. It is estimating the value of f (a + h) by assuming that, near to a, f (x) can be replaced by the straight line through (a, f (a)) with slope f'(a).

Definition The linear function is called the best linear approximation to f near the point (a,b). It is also called the linearization of f near (a,b) or the local linearization of f.
