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