A simple set of logic
A set has four properties. The elements of an extension set can be anything.
The elements in a deterministic set must be deterministic. For example, a good student does not have this attribute because its concept is vague.
The elements in an anisotropic set must be unequal to each other, and an element cannot appear repeatedly.
Elements in an unordered set are independent of order.
Two functions
This is an important point, but it's hard to say. When doing special training, such as quadratic function, exponential logarithmic function, etc. You should master several function ideas, such as constructing functions, combining symmetry with equations, exchanging elements, etc.
Three series
This is also an important question type. When doing the problem, we should have a whole idea, substitute it as a whole, separate the equivalence from the arithmetic, and pay attention to the connection, so as to do it well. It is necessary to observe the form of series to judge what series is, and to master several methods of finding the series of derived formulas, as well as summation formulas and summation methods, such as eliminating split terms, dislocation subtraction, formula method and grouping summation method.
trigonometric function
Trigonometric function is not an examination question, but an application knowledge point. Just remember the trigonometric function value at a special angle and some important theorems.
Five-plane vector
This is an abstract difficulty in the combination of geometry and algebra. When combining structures, you should have skills, mainly mastering the basic knowledge, paying attention to expansion and doing more problems. There are many kinds of questions, so you can have ideas when you combine the structure, which can simplify the problem and help improve the efficiency of doing the problem.
Mathematics in senior one is just an introduction. As long as you have a good grasp of the foundation, you won't have much problem in doing the problem, and you can get 130 in math.
