There are 2 questions in this calculation: for each question, the 2 derivative of x is calculated.
Note that variables are case sensitive.\[ \begin{equation}\begin{split}[1/2]Find\ the\ second\ derivative\ of\ function\ x - xy\ with\ respect\ to\ x:\\\end{split}\end{equation} \]
\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = x - yx\\&\color{blue}{The\ first\ derivative\ function:}\\&\frac{d\left( x - yx\right)}{dx}\\=&1 - y\\=& - y + 1\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( - y + 1\right)}{dx}\\=& - 0 + 0\\=&0\\ \end{split}\end{equation} \]\[ \begin{equation}\begin{split}[2/2]Find\ the\ second\ derivative\ of\ function\ x - 2xy - xy*2\ with\ respect\ to\ x:\\\end{split}\end{equation} \]
\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = x - 4yx\\&\color{blue}{The\ first\ derivative\ function:}\\&\frac{d\left( x - 4yx\right)}{dx}\\=&1 - 4y\\=& - 4y + 1\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( - 4y + 1\right)}{dx}\\=& - 0 + 0\\=&0\\ \end{split}\end{equation} \]Your problem has not been solved here?
