1 Find the limit-you need to know when to replace infinitesimal, when to use Robida's law, and there are two important limits.

2 Find the integral-you need to know the integral formula, the integral method of substitution, and the integral rule by parts.

3 derivative-you need to know the method of derivative and partial derivative.

4 Find the extreme value and inflection point-what are the conditions for knowing that the results of 1 derivative and 2 derivative are the extreme value point and inflection point respectively?

5 Find the area or volume of the geometric body-you need to know what the geometric meaning of the integral is. As long as you understand the geometric meaning, this kind of problem will be solved.

The focus of the exam should be only these, and the questions from the college entrance examination are not very difficult. If all this is understood, 80 points should be no problem. You can ask me if you don't understand.

I must make it clear.
