There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ ln(sqrt({\frac{1}{x}}^{2}))\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = ln(sqrt(\frac{1}{x^{2}}))\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( ln(sqrt(\frac{1}{x^{2}}))\right)}{dx}\\=&\frac{-2*\frac{1}{2}}{(sqrt(\frac{1}{x^{2}}))x^{3}(\frac{1}{x^{2}})^{\frac{1}{2}}}\\=&\frac{-1}{x^{2}sqrt(\frac{1}{x^{2}})}\\ \end{split}\end{equation} \]
