The cauchy–schwarz inequality
數學上，柯西-施瓦茨不等式，又稱施瓦茨不等式或柯西-布尼亞科夫斯基-施瓦茨不等式，是一條很多場合都用得上的不等式；例如線性代數的矢量，數學分析的無窮級數和乘積的積分，和概率論的方差和協方差。它被认为是最重要的数学不等式之一。它有一些推广，如赫尔德不等式。 不等式以奧古斯丁·路易·柯西（Augustin Louis Cauchy），赫爾曼·阿曼杜斯·施瓦茨（Hermann Amandus Schwarz），和維克托·雅科夫列維奇·布尼亞科夫斯基（英语：Viktor_Bunyakovsky）… 網頁In this video I provide a super quick proof of the Cauchy-Schwarz inequality using orthogonal projections.
