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