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