There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ 33{x}^{2} - 2{x}^{3} - 168x + 2\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 33x^{2} - 2x^{3} - 168x + 2\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 33x^{2} - 2x^{3} - 168x + 2\right)}{dx}\\=&33*2x - 2*3x^{2} - 168 + 0\\=&66x - 6x^{2} - 168\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 66x - 6x^{2} - 168\right)}{dx}\\=&66 - 6*2x + 0\\=& - 12x + 66\\ \end{split}\end{equation} \]
