Summary of Mathematical Derivative Formula of College Entrance Examination in 2022
Only by remembering the formula can we have ideas when doing the problem. Before NMET solves problems, it is necessary to fully associate and recall the same or similar knowledge points and questions as the original questions, and make full use of the ways, methods and conclusions in similar questions to solve existing problems.

The commonly used derivative formula 1, y=c(c is a constant) y'=0.

2、y=x^ny'=nx^(n- 1)

3、y=a^xy'=a^xlna

4、y=e^xy'=e^x

5、y=logaxy'=logae/x

6、y=lnxy'= 1/x

7、y=sinxy'=cosx

8、y=cosxy'=-sinx

9、y=tanxy'= 1/cos^2x

10、y=cotxy'=- 1/sin^2x

1 1、y=arcsinxy'= 1/√ 1-x^2

12、y=arccosxy'=- 1/√ 1-x^2

13、y=arctanxy'= 1/ 1+x^2

14、y=arccotxy'=- 1/ 1+x^2

The order of answering skills in the college entrance examination: from the beginning of the volume.

Generally speaking, the whole volume is roughly arranged from easy to difficult, so the correct way is to do the questions in turn from the beginning of the volume, from easy to difficult, and finally attack. Some candidates are willing to start with the difficult questions at the end of the paper. They think there is nothing wrong with the problem before them. Success or failure depends on how to do the final problem of the paper. At first, they were the clearest. Doing the most difficult questions first has high success rate and good effect. They want to win by attacking and ensure the overall victory. This idea seems reasonable, but it is actually wrong.

Generally speaking, the questions at the end of the paper are more difficult, except for some students with particularly high level, who do not have a good grasp of the questions. It probably took a lot of time, but I didn't finish the topic successfully. Most of your thoughts are disturbed at this time, and because you spent a lot of time and didn't do other questions, you will inevitably panic. If you do the previous questions in a flustered way, the effect will be greatly reduced.

However, it has no determination to do the questions in turn. Although a college entrance examination paper is generally easy first and then difficult, it is common to have problems in front of it, especially in the middle. Only when the degree of persistence is appropriate can we bypass the problem and do the guaranteed questions first, so as to score as many points as possible.
