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