lim e^3x-1/sinx,求值,x->0

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→0)[e^x-e^(-x)]/sinx=? x-0 lim(e^x-e^-x)/sinx lim ln(e^sinx) x趋向0
