There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{(In(-3x))}{e^{x}}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{-3Inx}{e^{x}}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{-3Inx}{e^{x}}\right)}{dx}\\=&\frac{-3In}{e^{x}} - \frac{3Inx*-e^{x}}{e^{{x}*{2}}}\\=&\frac{-3In}{e^{x}} + \frac{3Inx}{e^{x}}\\ \end{split}\end{equation} \]
