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