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