lim sin2x／sin5x (x→0),求详细过程

求(x→0)lim(sin2x/sin5x)的极限, 2.3计算极限lim(x→0) sin2x / sin5x lim sin2x／sin5x (x→0),求详细过程 极限lim x 趋于0 sin2x/sin5x lim,x->0,(sin5x)分之（sin2x)=? 求(x→∞)lim(sin2x/sin5x)的极限, 求下列极限 lim sin2x/sin5x (x–>0) lim(x→0)(sin5x)/x=? lim（x→0）sin5X/sin3X 求极限limx→0(x-sin2x/x+sin5x) lim(x→0) sin5x/6x= lim(x→0)sin5x/3x 的极限 lim（x →0）sin5x/tan2x怎么求, 计算lim（x→0）sin3x/sin5x lim(x→0+)[ln(sin5x)]/[ln(sin3x)] 这题咋做 lim（x→0）tan3x/sin5x=? lim(x→0)（x-sin2x）/（x+sin5x）怎么求这个极限?麻烦给详细步骤,我初学,高手请教 lim(x-0)(sin3x*sin5x)/(x^2)
