There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ {e}^{(2x)} + cos(3)x\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = {e}^{(2x)} + xcos(3)\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( {e}^{(2x)} + xcos(3)\right)}{dx}\\=&({e}^{(2x)}((2)ln(e) + \frac{(2x)(0)}{(e)})) + cos(3) + x*-sin(3)*0\\=&2{e}^{(2x)} + cos(3)\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 2{e}^{(2x)} + cos(3)\right)}{dx}\\=&2({e}^{(2x)}((2)ln(e) + \frac{(2x)(0)}{(e)})) + -sin(3)*0\\=&4{e}^{(2x)}\\ \end{split}\end{equation} \]
