There are 1 questions in this calculation: for each question, the 5 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 5th\ derivative\ of\ function\ (1 - cos(x))(x - sin(x))\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = - xcos(x) + sin(x)cos(x) + x - sin(x)\\\\ &\color{blue}{The\ 5th\ derivative\ of\ function:} \\=&16cos^{2}(x) - 16sin^{2}(x) - 6cos(x) + xsin(x)\\ \end{split}\end{equation} \]
