There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{-1}{10}{\frac{1}{(1 - x)}}^{2}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{\frac{-1}{10}}{(-x + 1)^{2}}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{\frac{-1}{10}}{(-x + 1)^{2}}\right)}{dx}\\=&\frac{-1}{10}(\frac{-2(-1 + 0)}{(-x + 1)^{3}})\\=&\frac{-1}{5(-x + 1)^{3}}\\ \end{split}\end{equation} \]
