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