There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 1 + (0.01x + 0.05)(0.02(y - x) + 0.5)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 0.0002yx - 0.0002x^{2} + 0.005x + 0.001y - 0.001x + 1.025\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 0.0002yx - 0.0002x^{2} + 0.005x + 0.001y - 0.001x + 1.025\right)}{dx}\\=&0.0002y - 0.0002*2x + 0.005 + 0 - 0.001 + 0\\=&0.0002y - 0.0004x + 0.004\\ \end{split}\end{equation} \]
