There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{sin(2)xx}{tan(3)} + 6\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{x^{2}sin(2)}{tan(3)} + 6\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{x^{2}sin(2)}{tan(3)} + 6\right)}{dx}\\=&\frac{2xsin(2)}{tan(3)} + \frac{x^{2}cos(2)*0}{tan(3)} + \frac{x^{2}sin(2)*-sec^{2}(3)(0)}{tan^{2}(3)} + 0\\=&\frac{2xsin(2)}{tan(3)}\\ \end{split}\end{equation} \]
