lim(x趋向于0)(1/x-1/e的2x次方-1)
举一反三
- lim（x/2）^（x/x-2）.x趋向于2!第二题：lim（e^（x）-1/x）.x趋向于0
- （1）lim(x-1)/sin(x-1),x趋向于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→0（x^2sin（1/x））/(e^x-1)
- lim(x趋向1)(x+2)/{(x^2)-1}=
