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