There are 1 questions in this calculation: for each question, the 1 derivative of q is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 20q - \frac{({q}^{2})}{10000}\ with\ respect\ to\ q：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 20q - \frac{1}{10000}q^{2}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 20q - \frac{1}{10000}q^{2}\right)}{dq}\\=&20 - \frac{1}{10000}*2q\\=& - \frac{q}{5000} + 20\\ \end{split}\end{equation} \]
