1 and A have higher knowledge difficulty and breadth than B;

2.a is mainly biased towards the knowledge structure of science and engineering, and B is biased towards the calculation of economics.

Details of specific differences are as follows:

A needs it, B doesn't.

(1) Master the properties and graphs of basic elementary functions.

(2) Grasp two criteria for the existence of limit and use them to find the limit.

(3) Some simple physical quantities can be described by derivatives.

(4) Understand the concepts of curvature and radius of curvature and calculate them.

(5) Understand the dichotomy and tangent method for finding approximate solutions of equations.

(6) Understand the concepts of tangent plane and normal plane of curves and tangent plane and normal plane of surfaces, and work out their equations.

(7) Triple integration

(8) Integration of curves and surfaces

(9) Vector Algebra and Spatial Analytic Geometry

B requires that integration and differentiation involve economic application problems and difference equations.

Extended data:

Refers to the object and method of mathematics, which is more complicated than elementary mathematics.

In a broad sense, all mathematics except elementary mathematics are advanced mathematics, and some call algebra, geometry, simple set theory and logic in middle school intermediate mathematics, which is the transition between elementary mathematics in primary and secondary schools and advanced mathematics in universities.

Generally speaking, advanced mathematics is a basic subject formed by calculus, algebra, geometry and their intersection.

The main contents include: limit, calculus, spatial analytic geometry and linear algebra, series, ordinary differential equations.

Basic subjects of postgraduate examination in engineering and science.

Advanced Mathematics (Class A) is an important basic theory course for undergraduate students of science and engineering, which serves to cultivate high-quality professionals needed by China's socialist modernization.

Advanced Mathematics (Class B) is an important basic theoretical course for undergraduates majoring in biology and chemistry, which serves to train high-quality professionals needed for China's socialist modernization.
