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