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