Differential calculus, including the calculation of derivative, is a set of theories about the rate of change, so that the function, velocity, acceleration and slope of a curve can be discussed with a set of commonly used symbols. Integral calculus, including the calculation of integral, provides a set of general methods for defining and calculating area and volume.

/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.
