第二个是求极限，也是很弱的题目arctanx*sin1/x的开方看上去很唬人，但其实sin1/x不会大于1，而arctanx在本题条件下极限是0。所以这道弱题的结果是ln2]]>Sep 2nd 2008 8:52PMhttp://cn.engadget.com/2008/09/02/15-bt-captcha/http://cn.engadget.com/2008/09/02/15-bt-captcha/Sep 2nd 2008 8:54PMhttp://cn.engadget.com/2008/09/02/15-bt-captcha/http://cn.engadget.com/2008/09/02/15-bt-captcha/我估计正确答案可能有4\5个. 脱裙子的和牛仔裤都看不清..]]>Sep 2nd 2008 10:20PMhttp://cn.engadget.com/2008/09/02/15-bt-captcha/http://cn.engadget.com/2008/09/02/15-bt-captcha/不过 昨天 我还遇到一个 叫我 先拼图 后注册的 我的天 晕倒]]>Sep 2nd 2008 8:54PMhttp://cn.engadget.com/2008/09/02/15-bt-captcha/http://cn.engadget.com/2008/09/02/15-bt-captcha/哈哈]]>Sep 2nd 2008 8:59PMhttp://cn.engadget.com/2008/09/02/15-bt-captcha/http://cn.engadget.com/2008/09/02/15-bt-captcha/Sep 2nd 2008 9:06PMhttp://cn.engadget.com/2008/09/02/15-bt-captcha/http://cn.engadget.com/2008/09/02/15-bt-captcha/
