lim(x—0) (1-cosx)/x

lim(x—0) (1-cosx)/x 求Lim(x→0)(sinx/x)^(cosx/1-cosx) lim(1-cosx)x趋向0, lim(x→0)(1/cosx)=? 求lim(1-cosx)/x^2求lim(1-COSX)/X^2X→0 证明 lim cosx=1 当x—0 lim(cosx)^(1/(1-cosx)).x趋向于0 大数lim(cosx)^(1/(1-cosx)).x趋向于0 lim(x->0)(ln(1+x)-x)/(cosx-1)=? lim（x→0） 1-cosx/x＋x lim(x→0)(e^x-cosx)/x=1? 1.x趋向0 lim (cosx-1)/x 2.x趋向0 lim sinx/x (1) lim(x->正无穷) x-lnx (2) lim(x->0+) cosx^1/x^2 lim(x→0)(cosx)^(1/ln(1+x^2)) Lim,x-0,(1/sinx)*(1/x-cosx/sinx)=? lim(x趋向0+)x/[(1-cosx)^(1/2)] lim x->0 cos(2x)-1 / cosx -1 = Lim(sinx/x)^1/(1-cosx) X趋近于0
