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