There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ \frac{1}{x} + ln(x)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{1}{x} + ln(x)\right)}{dx}\\=&\frac{-1}{x^{2}} + \frac{1}{(x)}\\=&\frac{-1}{x^{2}} + \frac{1}{x}\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( \frac{-1}{x^{2}} + \frac{1}{x}\right)}{dx}\\=&\frac{--2}{x^{3}} + \frac{-1}{x^{2}}\\ \end{split}\end{equation} \]
