There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ (\frac{(4 - {x}^{2})}{x}) + \frac{3x}{sqrt(2 - {b}^{2})}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{3x}{sqrt(-b^{2} + 2)} + \frac{4}{x} - x\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{3x}{sqrt(-b^{2} + 2)} + \frac{4}{x} - x\right)}{dx}\\=&\frac{3}{sqrt(-b^{2} + 2)} + \frac{3x*-(0 + 0)*\frac{1}{2}}{(-b^{2} + 2)(-b^{2} + 2)^{\frac{1}{2}}} + \frac{4*-1}{x^{2}} - 1\\=&\frac{3}{sqrt(-b^{2} + 2)} - \frac{4}{x^{2}} - 1\\ \end{split}\end{equation} \]
