问个题,这个题不让用洛必达定理,该怎么求极限,有朋友问了我,结果我也整不出[-] Naive_Might8074 | 1 points | Mar 28 2021 09:36:29
主要用等价无穷小替换和拉格朗日中值定理,我整整

太谢谢了

有年头没看了微积分忘的一干二净他妈的,还不给洛必达

太是了,我问其他人也是说不会,做题技巧都忘光了

谢谢了,底下有老哥点了我一下瞬间明白了

等价无穷小疯狂换就行,我算的答案是-1/2

草没想到这个

奶奶个腿,分子不是相减?怎么能换?
[-] Adept-Orchid1181 | 1 points | Mar 29 2021 03:21:05
咋不能换,除非像那种tanx-sinx直接得0的不好整,其他的都随便
[-] LAMSTREAM | 1 points | Mar 29 2021 03:45:30
我整懵了😅一年多前学的寄吧东西了

不做了,睡大觉

翻了半个多小时普林斯顿微积分读本,公式和定理都还大略记得,但就是太久没做,不知道该从哪里下手
