The first and second chapters are the basis, and there are relatively few topics for directly testing determinant and matrix, mainly relying on three or four chapters; These three chapters account for more scores.
The third chapter is matrix transformation and the solution of linear equations; Linear correlation between the rank of the fourth vector group and the vector group; In chapter 5, eigenvalue, similarity matrix and symmetry matrix will all cause big problems. In fact, find the answer after the textbook and do more exercises after class.
