Linearization is an approximation method used to estimate values of functions near a particular point by using their tangent lines.
A Taylor series is an expansion of a function into an infinite sum of terms, which allows for more accurate approximations than linearization alone.
Local Maximum/Minimum: These are points on a graph where nearby values are either greater (maximum) or smaller (minimum) than those around them.
A function is differentiable if it has derivatives defined for all points in its domain.
