x趋向0,((2-x)/(3-x))^1/x 答案是无穷大么?

Lim (1+x)(1+2x)(1+3x)-1除以x （x趋向0） （1+3x)^(2/sinx) x趋向0 求极限 lim(x^2+1)/(2x^+1) x趋向0 lim(1+3x)^3/x x趋向于0 计算lim(1+3x)^3/x x趋向0 lim(x趋向0) x^2 / (sin^2) * x/3 lim(x趋向0) x^2 / (sin^2) * x/3 lim x趋向0 (1+cos^2(1/x))^x lim(1-2x)^1/x x趋向于0 (2*arcsin x)/(3x)x趋向0的极限 lim(x趋向0)ln(1+sin x)/x^2 lim(x趋向于0)(x*cotx-1)/(x^2) x趋向于0,求ln(1+2x)/x lim(x趋向无穷)[1-(2/x)]^3x lim(1+3x)^(2/x)x趋向于零 lim(x趋向0)1-x^2-e^(-x^2)/xsin^3(2x) 求lim(x趋向0) (2x+e^3x)^1/x等于多少RT 极限,(e^x-1-x)^2/x^3sinx x趋向于0
