Compulsory one in senior high school: the emphasis is on functions, including sets, quadratic functions, abstract functions, composite functions, exponential functions, power functions, logarithmic functions, dichotomy and so on. Basically, these functions can be solved more conveniently with images, but of course some methods are also very important: substitution, assignment, separation of constants, integration, geometry, algebra and so on.

Compulsory 2: It is basically solid geometry, including three views, histogram, parallel proof, vertical proof, straight line equation, circle equation, the position relationship between straight line and circle, and the position relationship between circle and space coordinate system. These focus on geometric methods, drawing is very important, of course, algebraic methods also play a very important role in it!

Compulsory 3: basic statistics, which are generally very simple and can be seen at a glance!

Compulsory 4: Basically trigonometric functions, including sine function, cosine function, tangent function, vector and so on. Basically, it will be combined with compulsory one, so compulsory one must be solid! This makes trigonometric functions easier!

Compulsory 5: Basically a series of numbers, including: geometric series, arithmetic progression, etc. Generally speaking, it is to study the rules of a pile of miles and practice more.

How much is it!

There are elective courses, in contrast, elective courses are more difficult than compulsory courses, but they are all based on compulsory courses!
