There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{5sqrt(2)x}{2}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{5}{2}xsqrt(2)\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{5}{2}xsqrt(2)\right)}{dx}\\=&\frac{5}{2}sqrt(2) + \frac{5}{2}x*0*\frac{1}{2}*2^{\frac{1}{2}}\\=&\frac{5sqrt(2)}{2}\\ \end{split}\end{equation} \]
