There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{29.25x}{(40x + 2920)}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{29.25x}{(40x + 2920)}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{29.25x}{(40x + 2920)}\right)}{dx}\\=&29.25(\frac{-(40 + 0)}{(40x + 2920)^{2}})x + \frac{29.25}{(40x + 2920)}\\=&\frac{-1170x}{(40x + 2920)(40x + 2920)} + \frac{29.25}{(40x + 2920)}\\ \end{split}\end{equation} \]
