/kloc-In the second half of the 7th century, Newton, a great British scientist, and Leibniz, a German mathematician, independently studied and completed the creation of calculus in their respective countries on the basis of their predecessors' work, although this was only a very preliminary work.

Their greatest achievement is to connect two seemingly unrelated problems, one is the tangent problem (the central problem of differential calculus) and the other is the quadrature problem (the central problem of integral calculus)? .

Newton and Leibniz established calculus from intuitive infinitesimal, so this subject was also called infinitesimal analysis in the early days, which is the source of the name of the big branch of analysis in mathematics. Newton's research on calculus focused on kinematics, while Leibniz focused on geometry.

The application of calculus;

Calculus is developed in application. At first, Newton used calculus and differential equations to deduce Kepler's three laws of planetary motion from the law of universal gravitation.

Since then, calculus has greatly promoted the development of mathematics, as well as astronomy, mechanics, physics, chemistry, biology, engineering, economics and other natural sciences, social sciences and applied sciences.

And it is widely used in these disciplines, especially the appearance of computers is more conducive to the continuous development of these applications. Calculus, as a highly interdisciplinary subject, not only has strong practicability in physics and other natural sciences, but also has a strong role in promoting economics.
