Needless to say, in terms of functions, I feel that we should learn derivatives well. Derivative is a key point in the whole senior high school mathematics.
The series is divided into arithmetic progression and geometric progression. Remember the general formula The teacher will teach you a method called mathematical induction to find the general formula of the sequence. In addition, there are other methods, but mathematical induction is more important. Learn mathematical induction well. It will also be used in some proof questions.
Inequality will be a bit difficult to learn, but it will be easier to solve if you find the trick.
Note: There are many kinds of inequalities, such as absolute inequality, which involves changing the sign of absolute value. Fractional inequality involves whether the denominator of a molecule is 0. We must pay attention to these.
Circles and conic curves are generally connected by functions. The formula of conic curve must be kept in mind, so it is easy to mix, which will be very helpful for you to do more conic curve problems.
Learning solid geometry requires a certain sense of three dimensions. There is no problem with plane geometry, and it has a strong three-dimensional sense. It is not a dream to learn solid geometry well.
Learning permutation and combination, as the preparation of probability statistics, is the key point, which requires a certain degree of logical reasoning ability. I feel that you should do this kind of problems well and do more, which will help you master some tricks and be of great help to you.
Plural numbers are still easy to learn. I didn't focus on them when I studied, so I don't have any advice to give you.
Let's just say that what I said is not necessarily accurate, just for reference. I was in Liaoning the year before last, and my math score in the college entrance examination was 139. I hope my sword can help you.
