Mistakes are the easiest to lose points in the math exam of the college entrance examination. Because I accidentally fell into the error-prone trap set by the questioner. Most error-prone questions set traps on error-prone knowledge points. For example, set problems will set traps under special circumstances such as complete set and empty set, and derivative problems will be easily calculated repeatedly in a certain interval, and the nature of functions will be forgotten.

The following are some questions that are easy to make mistakes in preparing for the 2023 college entrance examination mathematics (national general):

-Set and its operation

-Functions and equations

-trigonometric function

-Plane vector

-Analytic geometry
