There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ 0.1219xxx - 47.8417xx + 2391.954x - 10407.912\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 0.1219x^{3} - 47.8417x^{2} + 2391.954x - 10407.912\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 0.1219x^{3} - 47.8417x^{2} + 2391.954x - 10407.912\right)}{dx}\\=&0.1219*3x^{2} - 47.8417*2x + 2391.954 + 0\\=&0.3657x^{2} - 95.6834x + 2391.954\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 0.3657x^{2} - 95.6834x + 2391.954\right)}{dx}\\=&0.3657*2x - 95.6834 + 0\\=&0.7314x - 95.6834\\ \end{split}\end{equation} \]
