There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{(16{x}^{3})}{({(1 + {x}^{2})}^{3})}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{16x^{3}}{(x^{2} + 1)^{3}}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{16x^{3}}{(x^{2} + 1)^{3}}\right)}{dx}\\=&16(\frac{-3(2x + 0)}{(x^{2} + 1)^{4}})x^{3} + \frac{16*3x^{2}}{(x^{2} + 1)^{3}}\\=&\frac{-96x^{4}}{(x^{2} + 1)^{4}} + \frac{48x^{2}}{(x^{2} + 1)^{3}}\\ \end{split}\end{equation} \]
