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