lim趋向0,x-sinx/x+sinx的极限怎么求?我是看第一章的,诺必塔还没学过.

lim x趋向0 x^2-sinx/x+sinx lim ln(e^sinx) x趋向0 求lim sinx^2/(sinx)^2 x趋向0 lim (x趋向于0)sin(sinx)/sinx lim(x趋向0)(x^3)/(x-sinx) 1.x趋向0 lim (cosx-1)/x 2.x趋向0 lim sinx/x lim(x趋向0)(sinx/x)等于1,那lim(x趋向0)(x/sinx)也等于1吗?是x/sinx啊,不是sinx/x 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(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? lim(x趋向于0)(tanx-sinx)/x^3=? lim(x趋向0)((sinx/x)+1)=2? lim x趋向于0 （tanx-sinx)/x lim (x趋向于0) sin(sinx)/x lim(x趋向于0)sinx/x=1,那么lim(x趋向于0)x/sinx=?怎么算?
