There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ ln(3x - sin(x))\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( ln(3x - sin(x))\right)}{dx}\\=&\frac{(3 - cos(x))}{(3x - sin(x))}\\=& - \frac{cos(x)}{(3x - sin(x))} + \frac{3}{(3x - sin(x))}\\ \end{split}\end{equation} \]
