There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 8{e}^{(4x)} - 9sin(3x) - 4x\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 8{e}^{(4x)} - 9sin(3x) - 4x\right)}{dx}\\=&8({e}^{(4x)}((4)ln(e) + \frac{(4x)(0)}{(e)})) - 9cos(3x)*3 - 4\\=&32{e}^{(4x)} - 27cos(3x) - 4\\ \end{split}\end{equation} \]
