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