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