There are 1 questions in this calculation: for each question, the 3 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ third\ derivative\ of\ function\ -1 + 2{x}^{4}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 2x^{4} - 1\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 2x^{4} - 1\right)}{dx}\\=&2*4x^{3} + 0\\=&8x^{3}\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 8x^{3}\right)}{dx}\\=&8*3x^{2}\\=&24x^{2}\\\\ &\color{blue}{The\ third\ derivative\ of\ function:} \\&\frac{d\left( 24x^{2}\right)}{dx}\\=&24*2x\\=&48x\\ \end{split}\end{equation} \]
