Li Yongle is the only part of linear algebra! ! ! As for Li Lin, I'm sorry, he was not famous when I took the postgraduate entrance examination. I don't know him at all. A few years later, I heard that he was a great candidate. This is not clear. After all, I have participated in the postgraduate entrance examination for many years! Li Lin has never heard of his class, but he wrote his paper. His article is really good. The topic is close to the difficulty of postgraduate entrance examination, and Li Yongle's composition is also good. Tang Jiafeng's composition is relatively basic, but Zhang Yu bought it but didn't do it. N numbers are located in different rows and columns, and the symbol of the item is determined by the parity of the arrangement. In Li Yongle's class or textbook, the summary of rank is the algebraic sum of the products of different rows and columns. The old man said that knowing so much about determinant is enough, which is too domineering! For example, the math test 1 can be about 100.

At the same time, I personally feel that for Math 3, Teacher Tang Jiafeng's class is completely sufficient. If you can thoroughly understand Mr. Tang's class, there is not much problem with Math Test 3 140. Whose class you listen to depends on your background. If there is no foundation, it is absolutely no problem to listen to Tang Jiafeng. I've basically been listening to Tang Jiafeng. He speaks very delicately and asks good questions. I listened to the online classes of Tang Jiafeng and Zhang Yu, but after listening to a few paragraphs, I stopped listening. Tang Jiafeng is too basic and too slow. Zhang Yu told a lot of jokes for the effect of the program, but it was actually ok.

Something happened in the math exam this year, and I changed my answer sheet twice. Counting the time to correct the answer sheet, I wasted an hour, which is equivalent to two hours and got 100 points. So, I really suggest that I should always follow Zhang Yu. If not, the foundation will be the same as soup stock. Strengthening the class with Zhang Yu depends on your foundation.
