There are 1 questions in this calculation: for each question, the 1 derivative of c is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 0.0716 - 0.0164ln(1 + 16.92c)\ with\ respect\ to\ c：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = - 0.0164ln(16.92c + 1) + 0.0716\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( - 0.0164ln(16.92c + 1) + 0.0716\right)}{dc}\\=& - \frac{0.0164(16.92 + 0)}{(16.92c + 1)} + 0\\=& - \frac{0.277488}{(16.92c + 1)}\\ \end{split}\end{equation} \]
