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