lim(sin2x)/3x＝ x趋向无穷大

lim sin2x/3x x趋向0 lim(sin2x)/3x＝ x趋向无穷大 求极限：lim(x趋向于无穷)x分之sin2x求极限：lim（x趋向于无穷）x分之sin2x lim(x趋向于无穷)(1+3/x)^(x-3) lim(x趋向无穷)[1-(2/x)]^3x lim趋向正无穷(x+1/x)^3x lim趋向正无穷(x+1/x)^3x lim x→正无穷 sin2x/3x =什么 lim(x+5/x-5)^x(x趋向无穷) 求lim x趋向于0（sin2x)/x? lim(sin2x)/(x^3+3x) x趋向于0快 lim x趋向无穷 {（2x^3+x)sin (2/x) }/ x^2+1 lim(arctan1/x)/(1/x),x趋向于无穷,为什么? x趋向无穷,则lim(x*a^x)= lim （n趋向无穷）（x/1+x)x次方 lim(x趋向无穷)-(x+1)+√(x^2+1) lim sin(x-1)/x-1 x趋向无穷 lim(x趋向无穷）(cos1/根号x)^2x
