There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{tanh(25t)}{(6(t - 0.08) + 1)}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{tanh(25t)}{(6t + 0.52)}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{tanh(25t)}{(6t + 0.52)}\right)}{dx}\\=&(\frac{-(0 + 0)}{(6t + 0.52)^{2}})tanh(25t) + \frac{sech^{2}(25t)*0}{(6t + 0.52)}\\=&0\\ \end{split}\end{equation} \]
