Generally speaking, it is divided into six partial determinants, matrix, vector, linear equations, eigenvalue and eigenvector of matrix. Quadratic linear algebra has a strong sense of integrity, each chapter is closely related, and there are many intertwined test sites, so it is easy to solve the synthesis problem of line generation, but line generation is relatively simple in number theory and probability theory. Because of his many concepts, it is not difficult, so it is easy for learners to learn and use them well. I think it is important to understand the concept in place, especially the concept and application of rank, the solution of linear equation and the characteristic matrix of characteristic vector, because these three test sites are easy to be similar, and the contract and quadratic form will cause big problems together, so we should pay attention to it. Generally speaking, line generation is not difficult, I hope my answer is helpful to you!
