To illustrate l'Hospital's rule, you should include a small epsilon. N1=:}.@([EMAIL PROTECTED])N=: _64 0 0 1 D1=:}.@([EMAIL PROTECTED])D=: _12 _1 1 ((N&p.%D&p.),.N1&p.%D1&p.) 4+1e_9 6.85714 6.85714
If you like, you might go further and try and implement limit (projecting what the epsilon would be as epsilon approaches zero), but the implementation of floating point numbrs can make this quite challenging. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
