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