lim(X一>0)(COSX)^[(1/SinX)^2]=
lim(X一>0)(COSX)^[(1/SinX)^2]=
lim x趋于0,sinx/(1+cosx)等于多少?
lim (sinx/x)*lim (1/cosx)=1 x趋于0的
lim(X->0)(tanX一SinX)/(X^3)=
1.lim(x→0)(2^1/2-(1+cosx)^1/2)/(sinx)^2
求极限:lim(x→0)(sinx)^2/[√(1+xsinx)-√(cosx)]
lim(x/sinx)x(趋近于0)为什么等于lim(cosx)x(趋近于0)
lim(x趋向于0)(1+sinx-cosx)/(1+sinβx-cosβx)
lim{[sinx+(x^2)*sin(1/x)]/[(1+cosx)ln(1+x)]}(x趋近于0)
lim{[3sinx+(x^2)*cos(1/x)]/[(1+cosx)ln(1+x)]}(x趋近于0)
lim(x→0)(1-cosx)[x-ln(1+tanx)]/(sinx)^4
求极限lim (sinx/x)^(1/1-cosx),x趋向于0
