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