What is calculous?

Calculus is a branch of mathematics that deals with the study of continuous change and motion. The two main branches of calculus are differential calculus and integral calculus. Differential calculus focuses on the rates of change of functions and their slopes, while integral calculus focuses on the accumulation of values of functions over intervals. Calculus is commonly used in science, engineering, economics, and many other fields to model and solve problems involving change and motion. Some of the fundamental concepts in calculus include limits, derivatives, and integrals. The history of calculus dates back to ancient Greece, but the modern form of calculus was developed in the 17th century by mathematicians such as Isaac Newton and Gottfried Leibniz.
