There are 1 questions in this calculation: for each question, the 1 derivative of t is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{(30.5(1 - e^{-0.05t}))}{t}\ with\ respect\ to\ t：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{-30.5e^{-0.05t}}{t} + \frac{30.5}{t}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{-30.5e^{-0.05t}}{t} + \frac{30.5}{t}\right)}{dt}\\=&\frac{-30.5*-e^{-0.05t}}{t^{2}} - \frac{30.5e^{-0.05t}*-0.05}{t} + \frac{30.5*-1}{t^{2}}\\ \end{split}\end{equation} \]
