Key Concepts

Fermat's Theorem on Stationary Points

Fermat's Theorem states that if a function has a local extremum (either a maximum or a minimum) at an interior point and is differentiable at that point, then the derivative at that point must be zero. This theorem provides a necessary condition for extrema under the assumption of differentiability, which is a crucial concept in calculus and optimization.

Local Maximum

A local maximum of a function means that at a certain point, the function's value is greater than or equal to its values at nearby points. This concept is fundamental in understanding the behavior of functions and is closely related to the idea of optimization, where one seeks to find the highest or lowest point in a specific region.

Differentiability

Differentiability refers to the property of a function that allows it to have a well-defined derivative at a point. When a function is differentiable at a point, it means that the function's rate of change at that point exists and can be computed, leading to important conclusions about the function’s behavior in a neighborhood around that point.
