There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{arctan(\frac{xπ}{3*2})*2*3}{π}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{6arctan(\frac{1}{6}πx)}{π}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{6arctan(\frac{1}{6}πx)}{π}\right)}{dx}\\=&\frac{6(\frac{(\frac{1}{6}π)}{(1 + (\frac{1}{6}πx)^{2})})}{π}\\=&\frac{1}{(\frac{1}{36}π^{2}x^{2} + 1)}\\ \end{split}\end{equation} \]
