There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 80 - (\frac{563360}{(9756 + x)}) - (\frac{x}{360})\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = - \frac{563360}{(x + 9756)} - \frac{1}{360}x + 80\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( - \frac{563360}{(x + 9756)} - \frac{1}{360}x + 80\right)}{dx}\\=& - 563360(\frac{-(1 + 0)}{(x + 9756)^{2}}) - \frac{1}{360} + 0\\=&\frac{563360}{(x + 9756)^{2}} - \frac{1}{360}\\ \end{split}\end{equation} \]
