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