2. Filling in the blanks is also a test of basic knowledge.
In the problem 3. 17, as long as the tolerance d of arithmetic progression and the common ratio q of geometric progression are set and substituted into the known conditions, it is easy to get the values of d and q, thus solving the problem of the general term of the sequence.
18, 19, and 20 can be said to be moderately difficult, and those with a good foundation can generally answer correctly.
Question 2 1 is a relatively basic question type. Personally, I think it may not be as difficult as 18 or19,20, but it is a little smaller.
The knowledge point of (1) is: find the derivative, and then discuss the derivative: it increases monotonically when it is greater than 0, and decreases monotonically when it is less than 0.
(2) It is not difficult to ask. By setting the coordinates of point P and using the derivative value of a point equal to the slope of the point, the problem can be solved.
Although it is generally believed that 22 questions are the finale, it is not difficult to ask this question first, and it can still be done in general. I won't go into details. The second question may be relatively difficult, but it can still be done with the idea of the topic. In short, this test paper is relatively simple, and it pays great attention to whether the basic knowledge of candidates is solid and solid. If you have a solid foundation and more problem-solving skills, you can still get high marks on this paper. Last reminder: In the future exams, it doesn't matter whether the students who take the college entrance examination continue to work hard for their ideals, and it doesn't matter if they don't work hard. After all, they can catch up with their efforts in the next exam, so don't be discouraged. I wish you all success in the college entrance examination! ! !
