There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ {(cos(2)x)}^{8}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = x^{8}cos^{8}(2)\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( x^{8}cos^{8}(2)\right)}{dx}\\=&8x^{7}cos^{8}(2) + x^{8}*-8cos^{7}(2)sin(2)*0\\=&8x^{7}cos^{8}(2)\\ \end{split}\end{equation} \]
