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