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