There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ (e^{-1000}x)(1800000x*2 + 2490x + 3)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 3602490x^{2}e^{-1000} + 3xe^{-1000}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 3602490x^{2}e^{-1000} + 3xe^{-1000}\right)}{dx}\\=&3602490*2xe^{-1000} + 3602490x^{2}e^{-1000}*0 + 3e^{-1000} + 3xe^{-1000}*0\\=&7204980xe^{-1000} + 3e^{-1000}\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 7204980xe^{-1000} + 3e^{-1000}\right)}{dx}\\=&7204980e^{-1000} + 7204980xe^{-1000}*0 + 3e^{-1000}*0\\=&7204980e^{-1000}\\ \end{split}\end{equation} \]
