There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ xsin(x)cot(x)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( xsin(x)cot(x)\right)}{dx}\\=&sin(x)cot(x) + xcos(x)cot(x) + xsin(x)*-csc^{2}(x)\\=&sin(x)cot(x) + xcos(x)cot(x) - xsin(x)csc^{2}(x)\\ \end{split}\end{equation} \]
