求lim x->无穷(sin2/x+cos1/x)^x

求lim x->无穷(sin2/x+cos1/x)^x 求lim(x^3(sin1/x-1/2*sin2/x)) x趋于无穷 求极限的疑惑：xsin2/x,x趋于无穷的极限,如果用极限运算法则：lim(x趋于无穷）xsin2/x=lim(x趋于无穷）x*lim(x趋于无穷）sin2/x,简单的分析lim(x趋于无穷）x趋于无穷,lim(x趋于无穷）sin2/x趋于零（因 x趋于无穷,lim(2x^2+1/x+2)sin2/x的值是多少 求极限lim（x-->无穷）（（2x^3+x）sin2/x）/(x^2+1)讲讲方法,有过程最好, 求limx->无穷[1/sin3/x-1/sin2/x] 求lim(x->&无穷)sinn/n,求lim(x->无穷)sin(1/n) lim(x趋近无穷)(1+2/x)^x怎么求 【求极限】(x趋向正无穷)lim((x^2)/arctanx). 求lim x(π/2-arctanx).x趋于无穷 已知lim(x趋于无穷)【 f(x)-ax-b】=0.求lim(x趋于无穷)【f(x)/x】 lim((x+sinx)/(x-cosx))x->无穷 求极限 lim(x趋向无穷)[(x+1)^(x+1)/x^x]sin(1/x) 求极限 x趋近于正无穷 Lim{[x^(1+x)]/[(1+x)^x]-x/e} 求：lim(1-5/x)^xx趋于无穷 求lim(n趋向于正无穷)(x^n)/n! lim当趋向于无穷时sin2/x等价于2/x吗?是和2/x等价,为什么不和1/x等价呢? lim x趋于π sin{2(X-π)/(X-π)}求极限lim x趋于π {sin2(X-π)/(X-π)}求极限
