Maybe methods could be called eval_derivate(), eval_integrate()? (not sure if those are the correct english terms) And another issue: one-liners should have brackets too: if (abs($est - $last) < $epsilon * abs($est)) { return $est; } instead of: if (abs($est - $last) < $epsilon * abs($est)) return $est;
