What optional modules are there in Zhejiang college entrance examination?
In the past two years since the reform of college entrance examination in Zhejiang, the contents of elective modules have been added. In the past two years, it should be said that the two problems in mathematics belong to the content that is easy to get points. Mathematics elective course 1B has four books, in which the history of mathematics and the multiple-choice question of inequality are combined to form a question, with a score of *** 10, matrix transformation, coordinate system and parameter equation combined to form a question, * * *. Among them, the history of mathematics is basically not tested, and inequality clearly stipulates that ranking inequality is not tested, that is to say, only basic inequality and Cauchy inequality are tested. This content is helpful for the mathematics study of compulsory courses, and it is not too difficult to test1b. In addition, matrix transformation is not tested, and polar coordinates and parametric equations are the key points. This piece is definitely to be tested, but it won't be too difficult. Therefore, for students who have carefully studied the four books of 1B module,

Generally speaking, you have learned all the basic inequalities. You only need to master Cauchy inequality, the concept and usage of polar coordinates, and several formulas and usage of parametric equations as elective modules.
