There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ -0.000005{x}^{3} - 0.0004{x}^{2} + 0.0165x + 22.324\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = -0.000005x^{3} - 0.0004x^{2} + 0.0165x + 22.324\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( -0.000005x^{3} - 0.0004x^{2} + 0.0165x + 22.324\right)}{dx}\\=&-0.000005*3x^{2} - 0.0004*2x + 0.0165 + 0\\=&-0.000015x^{2} - 0.0008x + 0.0165\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( -0.000015x^{2} - 0.0008x + 0.0165\right)}{dx}\\=&-0.000015*2x - 0.0008 + 0\\=&-0.00003x - 0.0008\\ \end{split}\end{equation} \]
