Limx →π (SiNx / x) and limx →1 (1 + 1 / x) ^ X are used to find the limit. The difference between these two formulas and two important limit formulas is explained

Limx →π (SiNx / x) and limx →1 (1 + 1 / x) ^ X are used to find the limit. The difference between these two formulas and two important limit formulas is explained

limx→π(sinx/x)=0/π=0
limx→1(1+1/x)^x=(1+1/1)^1
These two limits are a / B type, that is, direct substitution type
Two important limits, we should pay attention to the difference of the approaching time of the variable x
lim(x-->0)sinx/x=1
lim(x-->∞) (1+1/x)^x=e
