Integral

Definition

An integral is a mathematical concept used to calculate areas, volumes, and accumulated quantities by finding antiderivatives or sums of infinitesimal values.

Analogy

Imagine an integral as a tool that measures how much water flows through a pipe over time. By integrating the flow rate function over time, you can determine the total amount of water that has passed through.
