There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ X + \frac{sin(4)X}{X} + cos(7)X\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = sin(4) + Xcos(7) + X\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( sin(4) + Xcos(7) + X\right)}{dx}\\=&cos(4)*0 + X*-sin(7)*0 + 0\\=&0\\ \end{split}\end{equation} \]
