There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ (xx + 1)(3x - 1)(1 - xxx)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = - 3x^{4} - 3x^{6} + 4x^{3} + x^{5} + 3x - x^{2} - 1\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( - 3x^{4} - 3x^{6} + 4x^{3} + x^{5} + 3x - x^{2} - 1\right)}{dx}\\=& - 3*4x^{3} - 3*6x^{5} + 4*3x^{2} + 5x^{4} + 3 - 2x + 0\\=& - 12x^{3} - 18x^{5} + 12x^{2} + 5x^{4} - 2x + 3\\ \end{split}\end{equation} \]
