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