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