There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 3cot(x) + csc(x)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 3cot(x) + csc(x)\right)}{dx}\\=&3*-csc^{2}(x) + -csc(x)cot(x)\\=&-3csc^{2}(x) - cot(x)csc(x)\\ \end{split}\end{equation} \]
