There are 1 questions in this calculation: for each question, the 5 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 5th\ derivative\ of\ function\ sech(x)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ \\ &\color{blue}{The\ 5th\ derivative\ of\ function:} \\=&-61tanh(x)sech^{5}(x) + 58tanh^{3}(x)sech^{3}(x) - tanh^{5}(x)sech(x)\\ \end{split}\end{equation} \]
