摘要
高等数学中的limx→0sinx/=1与limx→∞（1+1/x）x=e是微积分中两个重要极限公式。通过考察两个极限公式的实际应用可见,它们各有两个本质特征。学生如果能正确理解和掌握它们,某些函数的极限求证,将变得十分简便。
lim x→0sinx/x=1 and limx→∞(1+1/x)x = e are 2 important limit formulae in calculus, which haverespectively 2in-being characteristics. If the students get a full understanding of and then master them, as the author holds, it will be very easy for them to work cut the limit problems of function.
