There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{arctan(3)*180}{π*2650}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{\frac{18}{265}arctan(3)}{π}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{\frac{18}{265}arctan(3)}{π}\right)}{dx}\\=&\frac{\frac{18}{265}(\frac{(0)}{(1 + (3)^{2})})}{π}\\=&\frac{0}{265}\\ \end{split}\end{equation} \]
