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