摘要
二元函数的极限较一元函数复杂,本文专门针对二元函数的极限作了较详细的探讨,对可能涉及的几种常见题型都进行了分析探讨,并给出了相应有效的解决方法,以解答学生在学习的过程中碰到的各种问题给予帮助。
The limit of dual function is more complex than unary function, the paper specifically for binary function limits made more detailed discussion on the kinds of questions, analyzed and discussed several common questions that may be involved, and put forward corresponding effective solution, to help to answer various problems encountered from students in the learning process.
