1, basic law of derivative: derivative law of product; Derivation rule of quotient; Chain derivative rule of implicit function.
2. Calculus is a branch of mathematics that studies limit, differential calculus, integral calculus and infinite series, and has become an important part of modern university education. Historically, calculus used to refer to infinitesimal calculations. More essentially, calculus is a study of change, just as geometry is a study of shape and algebra is a study of algebraic operations and solutions. Calculus is also called "elementary mathematical analysis"
3. Calculus is a branch of mathematics, which 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.
