There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ (1 - e^{-{(\frac{(x - 180)}{120})}^{2.13}})\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = - e^{-0.0083333333333x + 1.5} + 1\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( - e^{-0.0083333333333x + 1.5} + 1\right)}{dx}\\=& - e^{-0.0083333333333x + 1.5}(-0.0083333333333 + 0) + 0\\=& - -0.0083333333333e^{-0.0083333333333x + 1.5}\\ \end{split}\end{equation} \]
