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