There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 4 - \frac{3{(100 - x)}^{2}}{1600}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = - \frac{3}{1600}x^{2} + \frac{3}{8}x - \frac{59}{4}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( - \frac{3}{1600}x^{2} + \frac{3}{8}x - \frac{59}{4}\right)}{dx}\\=& - \frac{3}{1600}*2x + \frac{3}{8} + 0\\=& - \frac{3x}{800} + \frac{3}{8}\\ \end{split}\end{equation} \]
