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