Calculus is one of the greatest achievements of the human intellect. Calculus is the foundation of modern mathematics and almost all other branches of modern science.
Inspired by problems in astronomy, Newton and Leibniz developed the ideas of calculus three hundred years ago. Since then, each century has demonstrated the power of calculus to illuminate questions in mathematics, engineering, and the social and biological sciences.
In the course of calculus, much attention is paid to concepts and solving problems, and the underlying theory and proofs of important results are also emphasized.
Calculus can be mainly catalogued as differential theory and integral theory, or from other point of view, single variable calculus and multi-variable calculus. Calculus is one of the most important courses for the university students who major in science and engineering.
