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