Calculus - The Mathematics of Change

Graphs representing the derivative and integral functions


Calculus is a branch of mathematics that focuses on rates of change (differential calculus) and accumulation of quantities (integral calculus). Developed independently by Isaac Newton and Gottfried Wilhelm Leibniz in the late 17th century, calculus has widespread applications in various fields like physics, engineering, computer science, economics, statistics, and more.

The Foundations of Calculus


The concept of limits is foundational in calculus. It provides a way to understand the behavior of functions at a particular point.


A function describes a relation between an input and an output. In calculus, we often examine how functions behave as their input changes.

Differential Calculus

Differential calculus concerns itself with understanding how a function changes as its input changes. The derivative represents the rate at which a quantity changes and is a core concept in this subfield.

Notable Concepts

  • Derivative: The rate of change of a function.
  • Slope of the tangent line: The derivative represented geometrically.

Integral Calculus

Integral calculus, on the other hand, deals with the accumulation of quantities. It is essentially the reverse operation of the derivative and provides ways to calculate areas under curves, among other things.

Notable Concepts

  • Integral: The antiderivative, or the accumulated quantity.
  • Definite and indefinite integrals: Types of integrals depending on whether the limits are specified.
