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