There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 4sqrt(25 - {x}^{2})\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 4sqrt(-x^{2} + 25)\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 4sqrt(-x^{2} + 25)\right)}{dx}\\=&\frac{4(-2x + 0)*\frac{1}{2}}{(-x^{2} + 25)^{\frac{1}{2}}}\\=&\frac{-4x}{(-x^{2} + 25)^{\frac{1}{2}}}\\ \end{split}\end{equation} \]
