求极限(x->0) lim [ cot X*(1/sin X-1/x) ]
求极限,lim x趋于0 x * sin 1/x
求极限lim(x-->0)x^2 sin(1/x),
lim x趋向0 1/x∧2— cot∧2x 求极限
x →0时lim(1+x^2)^cot^2x求极限要详细过程.
lim x->0(sqrt(sin(1/x^2)) 求极限
求极限 lim sin(x^2 * sin (1/x))/x x->0
求极限 ((sin(x^3+x^2-x)+sin x) /x x→0 已知lim sinx/x=1
求极限LIM(趋近与0)(cot^2 *x-1/x^2)
求极限 lim(x趋向无穷)[(x+1)^(x+1)/x^x]sin(1/x)
x趋向于0 lim(1+tanx)^1-2cot 求极限
求极限:lim x→0 ln[1+sin^2(x)]/[e^(x^2)-1]
求极限lim(x→0) sin(1-x)/(1-x^2)
