There are 1 questions in this calculation: for each question, the 6 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 6th\ derivative\ of\ function\ 2sin(x) - 6cos(x) - xxxxxxxxxxxxxxxsin(x)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 2sin(x) - 6cos(x) - x^{15}sin(x)\\\\ &\color{blue}{The\ 6th\ derivative\ of\ function:} \\=&-2sin(x) + 6cos(x) - 3603600x^{9}sin(x) - 2162160x^{10}cos(x) + 491400x^{11}sin(x) + 54600x^{12}cos(x) - 3150x^{13}sin(x) - 90x^{14}cos(x) + x^{15}sin(x)\\ \end{split}\end{equation} \]
