There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ 0.0016{x}^{3} - 0.0404{x}^{2} + 0.4708x + 35.925\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 0.0016x^{3} - 0.0404x^{2} + 0.4708x + 35.925\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 0.0016x^{3} - 0.0404x^{2} + 0.4708x + 35.925\right)}{dx}\\=&0.0016*3x^{2} - 0.0404*2x + 0.4708 + 0\\=&0.0048x^{2} - 0.0808x + 0.4708\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 0.0048x^{2} - 0.0808x + 0.4708\right)}{dx}\\=&0.0048*2x - 0.0808 + 0\\=&0.0096x - 0.0808\\ \end{split}\end{equation} \]
