同学们在学习数学时接触最多的是等式,也许当时在大家看来,数学就是等式的天地,其实不然,不等式才是数学基本结果的主角.因为不等式的证明相对等式更困难、方法也更多样,研究不等式的空间也相对较大,所以很多数学家都对此进行了深入的研究.柯西便是其中一位.柯西是一位颇有建树的数学家,尤其在对不等式的研究方面取得了很大的成就,“柯西不等式”就是以他的名字命名的. Students are the most exposed in the study of mathematics is the equation, perhaps at that time in everyone’s view, mathematics is the world of equations, it is not true, inequality is the protagonist of the basic results of mathematics because inequalities prove that the relative equality is more difficult, the method Is also more diverse, the space for research inequality is relatively large, so many mathematicians have carried out in-depth study of this.Cosi is one of them.Casei is a well-established mathematician, especially in Great achievements have been made in the study of inequalities. The Cauchy inequality is named after him.
