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