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