There are 1 questions in this calculation: for each question, the 1 derivative of y is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{5{\frac{1}{(5y + 6)}}^{1}}{2}\ with\ respect\ to\ y：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{\frac{5}{2}}{(5y + 6)}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{\frac{5}{2}}{(5y + 6)}\right)}{dy}\\=&\frac{5}{2}(\frac{-(5 + 0)}{(5y + 6)^{2}})\\=&\frac{-25}{2(5y + 6)^{2}}\\ \end{split}\end{equation} \]
