:lim(xsin1/x+1/xsinx)x趋于0
:lim(xsin1/x+1/xsinx)x趋于0
lim(x~无穷)xsin1/x-1/xsinx
求极限公式,lim x趋于无穷,sinx/x x/sin1/x lim x趋于0,xsin1/x 1/xsinx xsi
求极限lim x→0 (1/xsinx+xsin1/x)
证明:Lim (1/xsinx-xsin1/x) =1 x→0
f(x)=xsin1/x 与 f(x)=1/xsinx 他们在取极限时,趋于0与趋于无穷大的值与区别,求详解,
求极限的一道题 lim(x趋于0) (xsin 1/x-1/xsinx)=
lim→0(xsin1/x+1/xsinx)用夹逼定理x/sinx=1解这条题目,请问这题的极限是多少?
lim x→0 1-cosx/xsinx
lim(x→0)(1-cos2x)/xsinx
X趋向0 lim(xsinx)/(1-cosx)
lim(x→0)(1-cos4x)/xsinx
