摘要
讨论了实二次型的半正定性,介绍了其在证明不等式中的应用。尤其是证明一般的初等不等式,对如何用高等数学方法解决初等数学问题作了一点尝试。
The author introduces the positive semi--definite property of real quadratic form and applies
it in proving inequality,especially in proving elementary inequality. It is an attempt to solve elementary
mathematical problems by high mathematical methods.
