There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ e^{I}*36{((L - x))}^{2}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 36L^{2}e^{I} - 72Lxe^{I} + 36x^{2}e^{I}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 36L^{2}e^{I} - 72Lxe^{I} + 36x^{2}e^{I}\right)}{dx}\\=&36L^{2}e^{I}*0 - 72Le^{I} - 72Lxe^{I}*0 + 36*2xe^{I} + 36x^{2}e^{I}*0\\=& - 72Le^{I} + 72xe^{I}\\ \end{split}\end{equation} \]
