摘要
介绍了化简二次型为标准形的主要方法:配方法、合同变换法、正交变换法,指出了使用3种方法时应注意的问题:既不能盲目,又要灵活、清醒,在此基础上提出教学时的一点建议.
The article firstly introduces the main methods to simplify quadratic form,which include match method,congruent transformation method and orthogonal transformation method. Then the article talks about some points for attention. When we apply the three methods,we should refrain from blind action and make a flexible calculation.Finally,the article provides some teaching suggestions about the simplification of quadratic form.
