The difference between high number B and high number A

Generally speaking, the difference between a and b is:

1 and A are both more difficult and wider than B.

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

The details are as follows: A has requirements, but B does not.

(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.

Summary: Generally speaking, you did well in the A test, and generally you will do well in the B test. If you have any questions, you can compare the basic teaching requirements of A and B by yourself. Generally, there are also science students who take an examination of economics, so it is recommended that students who study liberal arts and economics review and prepare for the exam with the difficulty of A as the standard.
