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