There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 22q - q(\frac{{q}^{3}}{48} - \frac{{q}^{2}}{4} + 12q + 18)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = - \frac{1}{48}q^{4} + \frac{1}{4}q^{3} - 12q^{2} + 4q\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( - \frac{1}{48}q^{4} + \frac{1}{4}q^{3} - 12q^{2} + 4q\right)}{dx}\\=& - 0 + 0 + 0 + 0\\=&0\\ \end{split}\end{equation} \]
