平方 Square (algebra)

(重定向自Square function)

代数中,一个数的平方是此数与它的本身相乘所得的乘积,一个元素的平方是此元素与它的本身相乘所得的乘积,记作x。平方也可视为求指数为2的幂的值。若x是正实数,这个乘积相当于一个边长为x的正方形的面积;如果x为虚数,则这个乘积为负数。如果x为非虚数的复数,则这个乘积也是复数。

如果实数y = x,就说yx的平方;如果同时x是非负数,那幺x就是y的平方根。如果一个整数 n 是某个整数的平方,则称 n 为一个完全平方数或平方数。有理数的平方一定是有理数,无理数的平方可以是有理数,也可以是无理数。

平方和通常指一些正整数的平方之和,整数的个数可以是有限个,也可以是无限多。 正整数的平方和公式如下:(可用数学归纳法证明)

The result of the mapping of the complex square function to a tiling of the complex plane

In mathematics, a square is the result of multiplying a number by itself. The verb "to square" is used to denote this operation. Squaring is the same as raising to the power 2, and is denoted by a superscript 2; for instance, the square of 3 may be written as 3, which is the number 9. In some cases when superscripts are not available, as for instance in programming languages or plain text files, the notations x^2 or x**2 may be used in place of x.
