There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ arccos({e}^{3}x)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = arccos(xe^{3})\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( arccos(xe^{3})\right)}{dx}\\=&(\frac{-(e^{3} + x*3e^{2}*0)}{((1 - (xe^{3})^{2})^{\frac{1}{2}})})\\=&\frac{-e^{3}}{(-x^{2}e^{6} + 1)^{\frac{1}{2}}}\\ \end{split}\end{equation} \]
