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