There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ {cos({x}^{5})}^{3}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = cos^{3}(x^{5})\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( cos^{3}(x^{5})\right)}{dx}\\=&-3cos^{2}(x^{5})sin(x^{5})*5x^{4}\\=&-15x^{4}sin(x^{5})cos^{2}(x^{5})\\ \end{split}\end{equation} \]
