There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ 2(sqrt(1 - {x}^{2}))\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 2sqrt(-x^{2} + 1)\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 2sqrt(-x^{2} + 1)\right)}{dx}\\=&\frac{2(-2x + 0)*\frac{1}{2}}{(-x^{2} + 1)^{\frac{1}{2}}}\\=&\frac{-2x}{(-x^{2} + 1)^{\frac{1}{2}}}\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( \frac{-2x}{(-x^{2} + 1)^{\frac{1}{2}}}\right)}{dx}\\=&-2(\frac{\frac{-1}{2}(-2x + 0)}{(-x^{2} + 1)^{\frac{3}{2}}})x - \frac{2}{(-x^{2} + 1)^{\frac{1}{2}}}\\=&\frac{-2x^{2}}{(-x^{2} + 1)^{\frac{3}{2}}} - \frac{2}{(-x^{2} + 1)^{\frac{1}{2}}}\\ \end{split}\end{equation} \]
