There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ 6{\frac{1}{x}}^{2} - 2x + 4\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{6}{x^{2}} - 2x + 4\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{6}{x^{2}} - 2x + 4\right)}{dx}\\=&\frac{6*-2}{x^{3}} - 2 + 0\\=&\frac{-12}{x^{3}} - 2\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( \frac{-12}{x^{3}} - 2\right)}{dx}\\=&\frac{-12*-3}{x^{4}} + 0\\=&\frac{36}{x^{4}}\\ \end{split}\end{equation} \]
