There are 1 questions in this calculation: for each question, the 1 derivative of t is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ {\frac{1}{t}}^{3}(t + 1)\ with\ respect\ to\ t：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{1}{t^{2}} + \frac{1}{t^{3}}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{1}{t^{2}} + \frac{1}{t^{3}}\right)}{dt}\\=&\frac{-2}{t^{3}} + \frac{-3}{t^{4}}\\=&\frac{-2}{t^{3}} - \frac{3}{t^{4}}\\ \end{split}\end{equation} \]
