There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ -0.0154{x}^{3} + 0.3516{x}^{2} - 2.508x + 66.593\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = -0.0154x^{3} + 0.3516x^{2} - 2.508x + 66.593\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( -0.0154x^{3} + 0.3516x^{2} - 2.508x + 66.593\right)}{dx}\\=&-0.0154*3x^{2} + 0.3516*2x - 2.508 + 0\\=&-0.0462x^{2} + 0.7032x - 2.508\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( -0.0462x^{2} + 0.7032x - 2.508\right)}{dx}\\=&-0.0462*2x + 0.7032 + 0\\=&-0.0924x + 0.7032\\ \end{split}\end{equation} \]
