Let's take a look at the outline and see what the test sites are. At the same time, according to the statistics and analysis of real questions, we can see which ones are frequent test sites and which ones are rare. Targeted review.

For example, the limit part is rarely proved in ξ-δ language, and the content is obscure. It is not worth spending a lot of time on this understanding. It is good to understand, but it does not affect the problem. As long as the same quantity can be substituted, several basic properties of limit calculation, such as grasping the big head, lim sinx/x, lim (1+655. The product limit of infinitesimal and bounded function is 0, and so on, there is basically no problem.

In the part of advanced mathematics, the first volume is the foundation, and there are many tests, but there are basically no big questions. At most, there is a big problem to prove the mean value theorem. The second volume mainly talks about the continuous differentiability of binary functions, differentiable concepts, chain derivatives, directional derivatives, plane and straight line calligraphy, and double integrals will be the focus.

The following curve and surface integrals will have a big problem, mainly Green's formula and Gaussian formula. Stokes formula is not very dependent, and there will be big problems in series and ordinary differential equations.

Plan your time well, don't stand still, grab a part and chew on it! Still the basic concepts and methods, no wonder there are not so many deviations!

Come on!
