Differential calculus

Definition

Differential calculus is a branch of mathematics that deals with the study of rates at which quantities change. It focuses on the concept of the derivative, which measures how a function's output value changes as its input value changes, providing insights into slopes of curves and the behavior of functions. This mathematical tool has deep connections with various historical contributions, enhancing our understanding of motion and change, especially in relation to notable figures and schools of thought.
