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