There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ 2X + {X}^{-1} - ln(X)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 2X + \frac{1}{X} - ln(X)\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 2X + \frac{1}{X} - ln(X)\right)}{dx}\\=&0 + 0 - \frac{0}{(X)}\\=& - 0\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( - 0\right)}{dx}\\=& - 0\\ \end{split}\end{equation} \]
