求lim(x-0)sinx-x/xsinx的极限

求大神解答：lim{xsin(2/x)+(2/x)sinx}等于什么?x趋于0 求(x-tanx)/(xsin^2x)的极限lim(x趋于0)x^2e^(1/x^2) lim(x趋于0+)x^sinx 求极限lim{[(sinx)/x]+xsin(1/2x)}x趋向无穷大, lim(x→∞)[sinx/x+xsin(1/2x)]答案是1/2.求过程 lim(sinx/x+xsin(1/x)) = x->无穷 lim(x→∞) (xsin(1/x)+1/x(sinx)) 求lim(n→0)[sin2x/x-xsin(2/x)] 极限lim(xsin*2/x+2/x*sinx)当x趋于0的极限 lim(x→0） x-(sinx)/xsin²x=?怎么解 求高数极限题 lim(x趋于正无穷）（xsin(π/x)+(π/x)sinx) 等于多少?求详解 求极限lim(x->0)x^sinx, lim x→∞ xsin(1/x)求极限 lim(x→∞) xsin(5/x)求极限 求极限lim(x→0){(2x-sin2x)/xsin^2x} lim(a^x-a^sinx)/(xsin^2x) ,x趋向于0. lim｛sinx/x - xsin(1/x)｝=x趋近于无穷 lim(x→∞) (xsin(3/x)+sinx /x)等于多少急! 求lim x→0,y→0 xsin[1/(x+y)]的极限
