There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ -0.00005{x}^{3} + 0.0016{x}^{2} + 0.0009x + 22.063\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = -0.00005x^{3} + 0.0016x^{2} + 0.0009x + 22.063\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( -0.00005x^{3} + 0.0016x^{2} + 0.0009x + 22.063\right)}{dx}\\=&-0.00005*3x^{2} + 0.0016*2x + 0.0009 + 0\\=&-0.00015x^{2} + 0.0032x + 0.0009\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( -0.00015x^{2} + 0.0032x + 0.0009\right)}{dx}\\=&-0.00015*2x + 0.0032 + 0\\=&-0.0003x + 0.0032\\ \end{split}\end{equation} \]
