lim(x趋向4)(sinx-sin4)/sin(x-4)=?呵呵

lim(x趋向4)(sinx-sin4)/sin(x-4)=?呵呵 lim ln(e^sinx) x趋向0 lim x趋向0 x^2-sinx/x+sinx 求lim sinx^2/(sinx)^2 x趋向0 lim (x趋向于0)sin(sinx)/sinx 1.x趋向0 lim (cosx-1)/x 2.x趋向0 lim sinx/x lim(4x-3)sinx/3x2-2x+5 x趋向无穷 求极限 lim(1-x^2-e^-x²)/(sinx^4) x趋向于0 lim(x趋向0)(x^3)/(x-sinx) lim x／（x+sinx）x趋向无穷大 怎么求 lim(x趋向于π/4) sinx-cosx/tan^2 x-1 lim(x趋向0)(arctanx-x)/sinx^3 lim(x趋向0)arctanx-sinx/x^3 lim ln(sinx/x)的极限.x趋向于0 lim（sinx/x） x趋向无穷大的极限? lim(x趋向于0)e^sinx/x 求lim x趋向于0(x-sinx)/tanx^3 Lim(X趋向0)(tanx-sinx)/x怎么解?
