There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{{e}^{x}sin(4x + 7)}{2}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{1}{2}{e}^{x}sin(4x + 7)\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{1}{2}{e}^{x}sin(4x + 7)\right)}{dx}\\=&\frac{1}{2}({e}^{x}((1)ln(e) + \frac{(x)(0)}{(e)}))sin(4x + 7) + \frac{1}{2}{e}^{x}cos(4x + 7)(4 + 0)\\=&\frac{{e}^{x}sin(4x + 7)}{2} + 2{e}^{x}cos(4x + 7)\\ \end{split}\end{equation} \]
