There are 1 questions in this calculation: for each question, the 15 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 15th\ derivative\ of\ function\ ({x}^{2})(sin(2x))\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = x^{2}sin(2x)\\\\ &\color{blue}{The\ 15th\ derivative\ of\ function:} \\=&1720320cos(2x) - 491520xsin(2x) - 32768x^{2}cos(2x)\\ \end{split}\end{equation} \]
