There are 1 questions in this calculation: for each question, the 3 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ third\ derivative\ of\ function\ {x}^{3} - 4{x}^{2} - 9x + 3\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = x^{3} - 4x^{2} - 9x + 3\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( x^{3} - 4x^{2} - 9x + 3\right)}{dx}\\=&3x^{2} - 4*2x - 9 + 0\\=&3x^{2} - 8x - 9\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 3x^{2} - 8x - 9\right)}{dx}\\=&3*2x - 8 + 0\\=&6x - 8\\\\ &\color{blue}{The\ third\ derivative\ of\ function:} \\&\frac{d\left( 6x - 8\right)}{dx}\\=&6 + 0\\=&6\\ \end{split}\end{equation} \]
