A PPROXIMATING WITH THE T ANGENT L INE Review- 3-F

Def: In many instances, finding a value of a function is difficult or impossible. With the use of Calculus techniques, we can approximate the function value by finding a y-value on a tangent line to the function. Since this method involves using a linear function (the tangent line function) at a nearby point, it is sometimes called a local linearization approximation.

Local Linearization
