2.如果变量x逐渐变化,趋近于定量ɑ,即它们的差的绝对值可以小于任何已知的正数时,定量ɑ叫做变量x的极限。可写成x
⇒ɑ, 或limx=ɑ。如数列1/2, 2/3, …, n/n+1 的极限是1, 写做 lim(n
⇒∞)n/n+1=1。{limit. If the variable x changes gradually and becomes sufficiently close to the definite quantity ɑ, that is, the absolute value of their difference has become smaller than any known positive number, the definite quantity ɑ is the limit of the variable x, expressed as x
⇒ɑ or limx=ɑ. For instance, the limit of the number sequence 1/2, 2/3, …, n/n+1 is 1, hence lim(n
⇒∞)n/n+1=1.}
