lim(x/x+1)^x+3求极限.
举一反三
- lim(x→∞)(1-1/(x+1))^(-x-1)=lim(x→∞)(1/(x+1))^(-x-1)lim(x→∞)(1-1/（x+1）)^(x+1)
- 求lim(x+1/x)^xx无穷大时极限
- 求极限lim(x-3)/(x^-9)(x→3)
- 求下列函数的极限求下列函数的极限lim(x→∞){1+e^(-x)};lim(x→1){|x-1|/(x-1)}
- 化简分式[img=229x50]1803072e13a5b44.png[/img]可以使用 A: Together[1/(x+1)-((x+3)/(x^2-1))(x^2-2x+1)/(x^2+4x+3)] B: Simplify[1⁄(x+1)-((x+3)⁄(x^2-1))((x^2-2x+1)⁄(x^2+4x+3))] C: Reduce[1⁄(x+1)-((x+3)⁄(x^2-1))((x^2-2x+1)⁄(x^2+4x+3))] D: Apart[1⁄(x+1)-((x+3)⁄(x^2-1))((x^2-2x+1)⁄(x^2+4x+3))]
