There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ e^{4}cos(8)x + lg(3) + sin(23)x\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = xe^{4}cos(8) + lg(3) + xsin(23)\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( xe^{4}cos(8) + lg(3) + xsin(23)\right)}{dx}\\=&e^{4}cos(8) + xe^{4}*0cos(8) + xe^{4}*-sin(8)*0 + \frac{0}{ln{10}(3)} + sin(23) + xcos(23)*0\\=&e^{4}cos(8) + sin(23)\\ \end{split}\end{equation} \]
