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