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