lim(sin1/x/1/x)在x趋向0的极限还等于1么?

lim(sin1/x/1/x)在x趋向0的极限还等于1么? lim(sinx-sin1)/(x-1) x趋向1时 求极限lim{(x^2/sinx)×sin1÷x}x趋向0 求极限Lim x趋向于1 (sinx-sin1)/(x-1) lim(X->0) sin1/X=? 求lim(sin1/x+cos1/x)^x,其中X趋向于无穷 为什么这道题目不能用洛必达法则x趋向于0,lim(x^2sin1/x)/sinx lim(n趋向无穷)=[（5x^2+1）/（3x-1）]sin1/x=? 1.x趋向0 lim (cosx-1)/x 2.x趋向0 lim sinx/x limx->0(x*sin1/x+1/x*sinx)=?lim x趋近于0 x*sin1/x=? x趋向0,（sin1/x）/x的极限 x^2sin1/x^2 极限X趋向于0 X→0,lim(sin1/x+cos1/x)^x 关于高等数学的几个问题求lim (arctanx/x) x趋向0lim sinx/(x^2*sin1/x) x-0lim (tanx-sinx)/x^2 x-0lim sinsinx^2/x^2 x-0要解答过程 lim(x→0)(x*sin1/x)/x^2极限为什么不存在?lim(x→0)(x*sin1/x)/x^2= lim(x→0)1/x*sin1/x 为什么这两个无穷小量不可以比较呢 lim(1-cosx)x趋向0, lim(x趋向0) 1-cos2x/xsinx x趋向0 lim xcotx
