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