There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 2{sin(-8{x}^{9})}^{2}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 2sin^{2}(-8x^{9})\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 2sin^{2}(-8x^{9})\right)}{dx}\\=&2*2sin(-8x^{9})cos(-8x^{9})*-8*9x^{8}\\=&-288x^{8}sin(-8x^{9})cos(-8x^{9})\\ \end{split}\end{equation} \]
