There are 1 questions in this calculation: for each question, the 9 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 9th\ derivative\ of\ function\ {x}^{2}sin(x)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = x^{2}sin(x)\\\\ &\color{blue}{The\ 9th\ derivative\ of\ function:} \\=&-72cos(x) + 18xsin(x) + x^{2}cos(x)\\ \end{split}\end{equation} \]
