There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ x - 6{\frac{1}{x}}^{3}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = x - \frac{6}{x^{3}}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( x - \frac{6}{x^{3}}\right)}{dx}\\=&1 - \frac{6*-3}{x^{4}}\\=&\frac{18}{x^{4}} + 1\\ \end{split}\end{equation} \]
