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