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