y=lim(x→0) (cos2x)^(1+cot^2x) =lim(x→0) e^ln(1-2xin^2x)/xin^2x是采用了哪个公式
y=lim (cos2x)^(1+cot^2x)y=lim(x→0) (cos2x)^(1+cot^2x)=lim(x→0) e^ln(1-2xin^2x)/xin^2x这部用的 ln 的什么公式,
lim(1-x)^(2/x) x->0
lim(x->0)((2-x)/(3-x))^1/x
lim(x→0)e^x-x-1/x^2
X趋于0 Lim(xlnx)=Lim(lnx/(1/x))=Lim(1/x/(-1/x^2))=Lim(-x)=0Lim(lnx/(1/x))=Lim(1/x/(-1/x^2))其中这步使怎么转化的?
(1) lim(x->正无穷) x-lnx (2) lim(x->0+) cosx^1/x^2
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
lim(x^2+1)/(2x^+1) x趋向0
lim(x->0) (x+1)^1/2-1 /x
帮求下x->0,lim[(1-x)/2]^[(1/x)+1],
lim(x->0)ln(1+2x)/e^x-1
lim(x→0)(1-2x)^1/x 极限?
lim x趋向0 (1+cos^2(1/x))^x
lim 2(1+x)^1/x x→0
lim x趋近于0 ((1+2^x)/)^(1/x)
lim[(1-e^(-x))^1/2]/x x趋于0
