求极限lim(1-1/2x)^x(x趋向无限大)
举一反三
- 求极限lim(In(x-1)-x)/tan(1/2x).x趋近于1+
- 求极限lim(x→1)(2/x^2-1)-(1/x-1)
- 下列极限计算正确的是( ). A: \(\lim \limits_{x \to 0} { { \left| x \right|} \over x} = 1\) B: \(\lim \limits_{x \to {0^ + }} { { \left| x \right|} \over x} = 1\) C: \(\lim \limits_{x \to 0} {(1 - {1 \over {2x}})^{2x}} = {e^{ - 1}}\) D: \(\lim \limits_{x \to \infty } {(1 - {1 \over {2x}})^{2x}} = e\)
- lim(x趋向1)(x+2)/{(x^2)-1}=
- 求极限lim(1-1/x)^kx,x趋于0,
