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