Is to solve the first three problems: trigonometric function, solid geometry, derivative.
① The key of trigonometric function lies in the simplification of analytical formula (translation and expansion), the drawing of trigonometric function, and the solution of period, maximum and monotone interval of function by five-point method.
② The key of solid geometry lies in finding the Z axis and proving its rationality. The key to writing coordinates lies in the construction of the bottom plan, and the coordinates of each point are written by writing two-dimensional coordinates.
③ The key of derivative lies in the image processing of derivative function. Some can be given directly according to the method of basic elementary function image. Or give the image of the derivative function by guessing the zero point (extreme point) of the derivative function.
④ Others: Select the first 8 questions of the question type and the first 4 questions of the fill-in-the-blank question. Students who score high should grasp the first of the last two questions, even the second of the quadratic curve. The second problem of conic curve is mainly about chord length and area. Active training before the exam helps students get high marks.
2. Art students' habit of doing math problems in college entrance examination
① Arrange the time reasonably. Art students do multiple-choice questions and fill-in-the-blank questions for an average of 3 minutes, and put 9 10 questions appropriately first. It is more appropriate to solve the choice and fill in the blanks in about 50 minutes. For the remaining 1 hour and 10 minute, the time allocation for the first three questions is 10 minute, 15 minute, the time allocation for the last two questions is 10 minute, and the remaining 10 minute is used to check the solving process of the first three questions.
(2) The choice of multiple-choice questions is generally evenly distributed. The last two multiple-choice questions really won't be done, and you must choose the one with the least number of occurrences.
