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