There are 1 questions in this calculation: for each question, the 5 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 5th\ derivative\ of\ function\ 3cos({x}^{4})\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 3cos(x^{4})\\\\ &\color{blue}{The\ 5th\ derivative\ of\ function:} \\=&-10080x^{3}cos(x^{4}) + 37440x^{7}sin(x^{4}) + 23040x^{11}cos(x^{4}) - 3072x^{15}sin(x^{4})\\ \end{split}\end{equation} \]
