2个回答

(1)lim(x趋向0)[(1+x)^0.5+(1-x)^0.5-2]/x^2 (2)lim(n趋向无穷)sin[[(n
lim x趋向0 (1+cos^2(1/x))^x
lim(1-2x)^1/x x趋向于0
lim x趋向于0 (√(1+x)-√(1+x^2))/(√(1+x)-1)
1、lim(tanx-sinx)/x的立方.x趋向0,2、lim{(2-x)/2}的2/x-1次方.x趋向0,3、lim
lim(1-(cosx)^(1/2))/(x(1-cos(x)^(1/2)) x趋向0
lim x趋向于0 (x^6-1)/(x^2-1)=?
lim(x趋向0)((sinx/x)+1)=2?
lim(x趋向0）1+x-e^x/x^2
为什么 lim(x趋向于0）(In(1+x)/x)=lim(x趋向于0）In(1+x)^(1/x)
