If we carefully look at the college entrance examination questions in previous years, it is not difficult to find that the general questions of Guangdong college entrance examination mathematics questions are: trigonometric function, probability, solid geometry, series, conic curve, combination of function and derivative. In fact, these questions are very regular! For example, (1) trigonometric functions often test properties (minimum positive period, monotonicity, maximum ...), (2) Needless to say, probability must be the probability of a certain situation; (3) Solid geometry generally proves parallelism first, verticality second and volume third; (4) The series test is the sum of the general formula and the first n phases of the series; (5) Conic curve is difficult, but the first question is very simple. Generally, it is an equation to find a curve. In fact, it is to test the known conditions for you to look at the topic. Can you find the abc value of the curve? The second question is the type question, which often tests the chord length of straight lines and curves. As long as it is this kind of problem, it is easy to do, and there are routines to solve the problem directly. (6) The combination of function and derivative, which is usually in the last line, is definitely difficult, but the first question is not difficult. This kind of question requires derivation, and you can get a point by only asking for derivation, and you can take derivation. The first problem needs to be solved. Suggest doing more exercise! Especially some real questions or simulated college entrance examination questions in previous years!
