1, calculus is a branch of mathematics that studies the differential and integral of functions and related concepts and applications in higher mathematics. It is the basic subject of mathematics. The content mainly includes limit, differential calculus, integral calculus and its application. Differential calculus, including the calculation of derivatives, is a set of theories about the rate of change. It makes the function, velocity, acceleration and curve slope can be discussed with a set of universal symbols. Integral calculus, including the calculation of integral, provides a set of general methods for defining and calculating area and volume.

2. The types of integrals mainly include definite integral, indefinite integral, Riemann integral, Dabo integral, Leberg integral, Riemann-Stitch integral and numerical integral.
