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