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