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