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