lim x->0 (e^3x -1)/sinx =

lim(x→0)[e^x-e^(-x)]/sinx=? lim (x→0) (e^x-x)^(1/sinx) lim(x→0)(1-x^2-e^-x)/sinx lim(x+e^2x)^(1/sinx) lim(e^tanx-e^3x)/sinx lim (e^sinx-e^x)/(sinx-x) lim X→0 [(1/(e^x-1))-(1/sinx)] lim e^x*((1/sinx)),x趋于0 极限函数计算lim( x^3 / sinx - x )lim( (1/e^x-1)-(1/x) ) 1.lim(x趋向0时)[x^2(1-cosX)]/[(1+e^X)(sinX)^3] lim(x+e^2x)^1/sinx(x趋向于0）=? 求极限 lim x-->0 （e^x-e^sinx）/(x^2+x)ln(1+x)arcsinx=?
