👉 Integrating calculus is a fundamental technique used to find the area under curves or between curves, essentially calculating accumulation over a defined interval. It involves summing up infinitesimally small parts of a function to determine total quantity, such as volume, mass, or work. The process relies on the Fundamental Theorem of Calculus, which links differentiation and integration: the derivative of an integral is the original function, and vice versa. By setting up an integral with a specific upper and lower limit, we can compute the area between these limits or the accumulation of a quantity over an interval. This powerful method extends beyond geometry, finding applications in physics, engineering, economics, and more, where understanding accumulation is crucial.
