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