There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ 0.000006{x}^{3} - 0.001{x}^{2} + 0.0285x + 22.226\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 0.000006x^{3} - 0.001x^{2} + 0.0285x + 22.226\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 0.000006x^{3} - 0.001x^{2} + 0.0285x + 22.226\right)}{dx}\\=&0.000006*3x^{2} - 0.001*2x + 0.0285 + 0\\=&0.000018x^{2} - 0.002x + 0.0285\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 0.000018x^{2} - 0.002x + 0.0285\right)}{dx}\\=&0.000018*2x - 0.002 + 0\\=&0.000036x - 0.002\\ \end{split}\end{equation} \]
