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