There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ 0.00002{x}^{3} - 0.0017{x}^{2} + 0.0393x + 22.49\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 0.00002x^{3} - 0.0017x^{2} + 0.0393x + 22.49\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 0.00002x^{3} - 0.0017x^{2} + 0.0393x + 22.49\right)}{dx}\\=&0.00002*3x^{2} - 0.0017*2x + 0.0393 + 0\\=&0.00006x^{2} - 0.0034x + 0.0393\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 0.00006x^{2} - 0.0034x + 0.0393\right)}{dx}\\=&0.00006*2x - 0.0034 + 0\\=&0.00012x - 0.0034\\ \end{split}\end{equation} \]
