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