极限lim x->0 (xsin2/x+2/xsinx)=?

极限lim x->0 (xsin2/x+2/xsinx)=? 求极限 lim(xsin2/x+sin3x/x) x趋向于无穷 lim(x→∞)(xsin2/x+sin3x/x) 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 lim x-0 sin2x/x 求极限 lim(x->0)arctan1/x求极限 急求高数极限答案lim(x->0)/x 求极限lim(x->0)x^sinx, 极限Lim(x->0)(sin3x)/x= 极限Lim(x->0)(sin3x)/x= lim x->0+ lncotx/lnx 求极限 求lim (x->0) 的极限? 极限练习题lim(n->0)(tanx/x) 极限题目lim(x->0)(tanx)^sinx 极限lim x 趋于0 sin2x/sin5x 求极限lim(x->0)(x+e^x)^2/x 求极限:lim(x->0) ln(sinx/x)/(x*x) 求极限 lim (x->0) 3x/(sinx-x) 求极限,lim x趋于0 x * sin 1/x
