There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ xsqrt(8) - x*2\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = xsqrt(8) - 2x\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( xsqrt(8) - 2x\right)}{dx}\\=&sqrt(8) + x*0*\frac{1}{2}*8^{\frac{1}{2}} - 2\\=&sqrt(8) - 2\\ \end{split}\end{equation} \]
