无穷小wúqióngxiǎo一个变量在变化过程中,绝对值永远小于任意小的已定正数,即以零为极限的变量,叫做无穷小。如1/2,在n取值1,2,3,4…的变化过程中就是无穷小。{infinitely small; infinitesimal; variable, the absolute value of which is always smaller than an arbitrarily small positive number in the process of varying, that is, variable with zero as its limit, called infinitely small. For instance, 1/2 is infinitely small in the process of varying when n is 1, 2, 3, 4 ...;}也叫also无限小{wúxiànxiǎo}。 |
