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