Mathematics for postgraduate entrance examination is tested twice. Matrix, determinant, linear correlation of vector group, linear equations, similarity matrix and quadratic form are two major questions in mathematics.

Quadratic form refers to a quadratic polynomial with n elements called quadratic form, that is, in a polynomial, the number of unknowns is arbitrary, but the degree of each term is 2. As one of the important contents of linear algebra, it originated from the study of transforming quadratic curve equation and quadric surface equation into standard form in geometry. Quadratic theory is related to the characteristics of the field.
