Differentiation

Definition

Differentiation is a mathematical process used to find the rate at which a function is changing at any given point, resulting in the derivative of that function. This concept is essential for analyzing functions, optimizing problems, and understanding changes in various applications. It plays a vital role in symbolic computation as it allows for the manipulation and transformation of mathematical expressions through algorithmic techniques.
