柯西不等式的应用

Application of Cauchy Schwarz's Inequality

柯西不等式是应用价值非常大的数学公式。它能推导空间点到平面及点到直线的距离公式,用它还能推导三角不等式、证明光行最速原理等数学物理结论,它还可以求一些比较难求的最值问题及一些比较难证的数学题目。

Cauchy Schwarz's inequality is an applied mathematical formula with great value.It can certify some phenomena of mathematical physics,such as the distance formula from the point in the air to the plane,triangle inequality,and the theory of light maximum speed and it can help find out some function maximum or minimum and other mathematical questions.
