Calculus is a branch of mathematics that deals with the study of change and motion. It consists of two main branches: differential calculus and integral calculus. Differential calculus focuses on the concept of derivatives, which measure the rate at which a quantity changes. Derivatives are used to analyze rates of change, find maximum and minimum values, and study the behavior of functions. Integral calculus, on the other hand, deals with integrals, which are used to calculate accumulated quantities or find the area under curves. Integrals can be seen as reverse operations of derivatives and are used in various fields such as physics, engineering, economics, and statistics. Calculus is widely applied in many scientific disciplines to model and solve problems involving continuous change. It provides powerful tools for understanding and quantifying complex phenomena in both theoretical and practical contexts.
