Calculus

Calculus is the branch of mathematics that deals with the finding and properties of derivatives and integrals of functions, by methods originally based on the summation of infinitesimal differences. The two main types are differential calculus and integral calculus. Differential calculus is the study of the definition, properties, and applications of the derivative of a function. Integral calculus is the study of the definitions, properties, and applications of two related concepts, the indefinite integral and the definite integral.
