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