There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ 0.0003{x}^{3} - 0.0016{x}^{2} + 0.0206x + 8.1195\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 0.0003x^{3} - 0.0016x^{2} + 0.0206x + 8.1195\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 0.0003x^{3} - 0.0016x^{2} + 0.0206x + 8.1195\right)}{dx}\\=&0.0003*3x^{2} - 0.0016*2x + 0.0206 + 0\\=&0.0009x^{2} - 0.0032x + 0.0206\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 0.0009x^{2} - 0.0032x + 0.0206\right)}{dx}\\=&0.0009*2x - 0.0032 + 0\\=&0.0018x - 0.0032\\ \end{split}\end{equation} \]
