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