20 13 Sichuan college entrance examination mathematics answering skills?
For mathematics, the knowledge points are relatively stable, and the questioners generally like to destroy the candidates according to the idea of "7 dizzy and 8 dead". Usually, the seventh question is a familiar scene, but it will make the candidates dumbfounded. The eighth question is mostly unheard of. Because the seventh question was shocked and bypassed the eighth question, the students could not play their due level smoothly, so many students lamented "Pit Dad, exactly the same". To deal with this proposition, we must focus on making innovative small questions before the exam, and the ideas of innovative small questions will be discussed in detail in the fifth lecture in spring. For the exam of 14, some districts will imitate the idea of last year's college entrance examination. If you ask for 5 points, you won't get 0 points. In other "compassionate" fields, there will be two problems, so we must solve the first one first, and the second one can be done according to our own ability, but don't make a mountain out of a molehill.

For solving the first three questions, the position of trigonometry, solid geometry and probability will not be shaken, but the emphasis may change, such as the transformation of trigonometric identities, whether the image of trigonometric functions has a good formula system and the details of answers will be the key to get full marks. The examination of solid geometry was influenced by the college entrance examination last year, so it will be more difficult to choose the spatial coordinate system and solve the point coordinates. We still have to deal with the choice of solid geometry and space vector direction. The rigorous writing habits of solid geometry will become the focus of the teacher's deduction. Probability test will no longer pay attention to all discrete random variables, but more integrate compulsory 3 and elective 2-3. Be sure to understand the meaning of the question before answering the question to avoid the situation of "making a mistake and losing all points".

How to adjust and discuss the monotonicity between derivative and conic curve, derivative or parameter will be the key to get high marks. The conic curve is still dominated by ellipse. It is a system from the selection of straight lines, the solution of straight line equations, who will disappear after the combination of straight lines and curves, and how to successfully establish algebraic equations to solve problems. Have a big picture and don't waste time blindly. The last question, the level of the questioners in each district is definitely not as clear as the college entrance examination, so the difficulty may not be too great. The ability to process new information and build new mathematical models is a step-by-step process, which cannot be achieved overnight.
