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