| Nov 6, 2020 at 23:32 | comment | added | Julian Newman | Thank you very much. But I'm confused about the line $(\log g'(x))' = \sum_{i = 1}^n (\log f_i'(x_i))' = \sum_{i = 1}^n \frac{f_i''(x_i)}{f_i'(x_i)}$. Since $x_i$ is itself a function of $x$, are you not missing factors in front of $\frac{f_i''(x_i)}{f_i'(x_i)}$? | |
