postscript
The first chapter will be multiple-choice questions for the college entrance examination.
The second chapter is a big question in the exam.
A multiple-choice question in probability examination
It's all about the college entrance examination, right?
Because every school is different several times and the order of learning books is different, what did you learn next semester?
Mathematics plays the most important role in the next semester of grade three! The last of the two questions in the senior high school entrance examination 10 is a quadratic function (affirmation), which means that the quadratic function is the finale, followed by a circle.
Don't think too much about the learning methods of mathematics next semester. Learning math skills is very important. Ask about sea tactics unless you are better than Euler. I don't think the sea tactics require you to be soft, but to do it selectively. Paying attention to quality rather than quantity is a technical activity, which challenges logical thinking. It is quite challenging to sum up all kinds of questions by doing questions, cultivate a good sense of questions and enhance self-confidence in the past. When I meet a big exam, I will be black-faced, and obviously I can't write the questions that are usually available. This is the nonsense of the problem. To put it bluntly, I usually rely on my own cleverness to do problems, or I will be soft in doing problems but never summarize the analysis results. I'll be dumbfounded next time.

After substituting f(x) into mathematics in the first semester of senior high school, add the first and last items, and add the second and penultimate items. After adding up, the total score is 1/2, and so on. * * There is (n+ 1)/2, that is, (n+ 1/2).

( 1)cos(3/2-a)= cos(3/2)* cosa-sin(3/2)* SINA =-SINA
(2)cos (Uyghur -A) = COS (Uyghur) *cosa-sin (Uyghur) * SINA =-COSA
