There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ -0.001{x}^{3} + 0.0177{x}^{2} + 0.0641x + 28.28\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = -0.001x^{3} + 0.0177x^{2} + 0.0641x + 28.28\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( -0.001x^{3} + 0.0177x^{2} + 0.0641x + 28.28\right)}{dx}\\=&-0.001*3x^{2} + 0.0177*2x + 0.0641 + 0\\=&-0.003x^{2} + 0.0354x + 0.0641\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( -0.003x^{2} + 0.0354x + 0.0641\right)}{dx}\\=&-0.003*2x + 0.0354 + 0\\=&-0.006x + 0.0354\\ \end{split}\end{equation} \]
