There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ -0.0021{x}^{3} + 0.0564{x}^{2} - 0.5201x + 8.2338\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = -0.0021x^{3} + 0.0564x^{2} - 0.5201x + 8.2338\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( -0.0021x^{3} + 0.0564x^{2} - 0.5201x + 8.2338\right)}{dx}\\=&-0.0021*3x^{2} + 0.0564*2x - 0.5201 + 0\\=&-0.0063x^{2} + 0.1128x - 0.5201\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( -0.0063x^{2} + 0.1128x - 0.5201\right)}{dx}\\=&-0.0063*2x + 0.1128 + 0\\=&-0.0126x + 0.1128\\ \end{split}\end{equation} \]
