There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ {(9 - 18x)}^{2} + \frac{9{(1 - 9x)}^{2}}{2}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{1377}{2}x^{2} - 405x + \frac{171}{2}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{1377}{2}x^{2} - 405x + \frac{171}{2}\right)}{dx}\\=&\frac{1377}{2}*2x - 405 + 0\\=&1377x - 405\\ \end{split}\end{equation} \]
