lim xsinx=?x趋无穷大

若lim(x趋近于x零f(x)=A,lim(x趋x零）g(x)=无穷大,x趋于x0 ,证明[f(x)+g(x)]不存在. lim(x→0)x/(xsinx)=0和lim(x→0)(xsinx)/x=1 lim(x→0)(1-cosx)/(xsinx)=? lim(x趋向于0)(cosx)^[1/(xsinx)]= 高等数学极限运算Lim[(x/x+1)-(1/x-1)]X趋向无穷大lim x^2[(1/x+1)-(1/x-1)]X趋 lim(x~无穷)xsin1/x-1/xsinx 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 lim x趋近于无穷大 (1-x)∧x=? 求 lim（x->无穷大）
