There are 1 questions in this calculation: for each question, the 9 derivative of z is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 9th\ derivative\ of\ function\ cos({z}^{2})\ with\ respect\ to\ z：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = cos(z^{2})\\\\ &\color{blue}{The\ 9th\ derivative\ of\ function:} \\=&-30240zsin(z^{2}) - 80640z^{3}cos(z^{2}) + 48384z^{5}sin(z^{2}) + 9216z^{7}cos(z^{2}) - 512z^{9}sin(z^{2})\\ \end{split}\end{equation} \]
