👉 Integral calculus is a branch of mathematics that focuses on calculating the accumulation of quantities, often dealing with areas under curves, volumes of solids, and changes over intervals. It is built around two main concepts: the definite integral and the indefinite integral. The definite integral evaluates to a specific value over a defined interval, representing the net area between a curve and the x-axis within that interval. The indefinite integral, on the other hand, finds a family of functions whose derivative is the given function, essentially solving for the original function from its derivative. This branch of calculus is fundamental in various fields, including physics, engineering, and economics, for modeling real-world phenomena like motion, growth, and optimization problems.
