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