There are 1 questions in this calculation: for each question, the 1 derivative of t is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ (1 + ln(t))et\ with\ respect\ to\ t：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = teln(t) + te\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( teln(t) + te\right)}{dt}\\=&eln(t) + t*0ln(t) + \frac{te}{(t)} + e + t*0\\=&eln(t) + 2e\\ \end{split}\end{equation} \]
