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