The number of asymptotes, the derivation of functions, and the transformation from polar coordinates to rectangular coordinates are all basic problems. The method is relatively fixed and should be done smoothly. In addition, most of the topics of line generation and probability also focus on the basics. Line generation investigates linear correlation, solves linear equations, and has quadratic canonical form. Probability is to examine whether everyone's basic skills are solid, especially the last two big questions, a two-dimensional discrete random variable and a two-dimensional continuous random variable, which we often practice and emphasize repeatedly. Therefore, the basic questions in the whole test paper should account for the vast majority.
Second, flexibility.
For example, the fourth multiple-choice question in the high number part, the convergence and divergence of known series, and the range of unknown parameters in turn are actually the convergence and divergence of series in turn. There is also the eighth question probability in the multiple-choice question. We know that the denominator in the definition of distribution is a formula with a root sign, and the denominator in this problem is an absolute value. Some students feel that there is no way to start, but if you think about it carefully, the absolute value can be expressed by the square root sign.
Third, it is comprehensive.
This is also a consistent feature of the postgraduate mathematics test questions. The teacher wants the 23 questions in a test paper to cover all the major test sites as comprehensively as possible, so almost all the questions can not be solved by one knowledge point, and multiple knowledge points need to be comprehensively used. For example, the simplest calculation limit in a big problem, in order to quickly calculate this limit, we need to be able to comprehensively use equivalent infinitesimal, Taylor formula, limit algorithm and other knowledge points, any part of which will cause obstacles to the solution of this problem.
