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