lim(x趋向于π/4) sinx-cosx/tan^2 x-1

lim(x趋向于π/4) sinx-cosx/tan^2 x-1 lim (x趋向于0)sin(sinx)/sinx 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趋向于0)(tanx-sinx)/x^3=? lim(tanx+sinx)/x∧2 x趋向于零 lim x趋向于0 （tanx-sinx)/x lim (x趋向于0) sin(sinx)/x lim x 趋向于无穷 (sinx+cosx)/x lim(x趋向于0)sinx/x=1,那么lim(x趋向于0)x/sinx=?怎么算? lim（x趋向于π）sinx/(x^2+π*x-2*π^2) lim(1-x^2-e^-x²)/(sinx^4) x趋向于0 lim(sinx)^tanx (x趋向于pai/2)求极限 计算lim(x趋向于π/2)(sinx)的tanx次方怎么计算? 计算lim(x趋向于π/2)(sinx)^tanx怎么计算? x趋向1 lim (sinx/x)等于多少?为什么?注意是趋向于1,不是0. 求极限(x趋向于0时）lim[sinx-sin(sinx)]/(sinx)^3
