There are 1 questions in this calculation: for each question, the 7 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 7th\ derivative\ of\ function\ 2ln(x) + \frac{({(x - 1)}^{2} + {y}^{2})}{(2{x}^{2})}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 2ln(x) - \frac{1}{x} + \frac{\frac{1}{2}}{x^{2}} + \frac{\frac{1}{2}y^{2}}{x^{2}} + \frac{1}{2}\\\\ &\color{blue}{The\ 7th\ derivative\ of\ function:} \\=&\frac{1440}{x^{7}} + \frac{5040}{x^{8}} - \frac{20160}{x^{9}} - \frac{20160y^{2}}{x^{9}}\\ \end{split}\end{equation} \]
