lim(1+3(tanx)^2)^(cotx)^2怎么做?
x趋于0 lim sinx-tanx/x^3=lim sinx/x×(cosx-1)/(x^2×cosx)是怎么通分的?x趋于0 lim sinx-tanx/x^3=lim sinx/x×(cosx-1)/(x^2×cosx)thank you
lim(tanx-sinx)/(sinx)3
lim (1+tanx)^1/2-(1+sinx)^1/2/x^3趋于0
求lim x趋近于0 sinx^3 tanx/(1-cosx^2)
lim(tanx-sinx)/x^3,x趋向0,求极限,是1/2吗?
lim(x->0)(1/(tanx)^2-1/(x)^2
lim[ln(1+x)+ln(1-x)]/(tanx)^2
lim(x->无穷)sinx-tanx/e^x^3-1
lim(1+3tanx)^cotx ,x→0的极限
lim(x趋于0)(tanx-sinx)/3x^2
lim(1+2tanx)^cotx (x趋向于0)
lim[三次根号下(1+tanx)-1]*[根号下(1+x^2)-1]/(tanx-sinx)
1.lim x->∞ (2x/x^2+1)*cosx 2..lim x->∞{ [(x^2-x)arctanx]/x^3-x-5}3..lim x->0 (e^x-e^-x-2x)/(x-sinx) 4..lim x->0 (sinx-x)/(x^3) 5..lim x->0 (x^2*tanx)/(x-tanx) 6..lim x->0 (1+3/x)^2x 7..lim x->0 (1+2x)^(3/sinx) 8.lim x->∞ (x/1+x)^(x-3) 9..li
利用函数极限求数列极限(例题)设函数f(x)=(tanx/x)^((1/(x^2))于是x趋于0 lim f(x) =x趋于0 lim(tan/x)^(1/(x^2))=e^lim x趋于0 ln (tanx/x)/(x^2)=e ^lim x趋于0 ((tan/x)-1)/(x^2)=e^lim x趋于0 (tanx-x)/(x^3)=e^1/3 lim x趋于0 (
求极限lim.tanx-sinx / x^3
lim(x->0)((x-arcsinx)/(tanx)^3)
lim(x->0+)(1/x)^tanx
