There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 5cos(2x - arccos(\frac{1}{2}))\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 5cos(2x - arccos(\frac{1}{2}))\right)}{dx}\\=&5*-sin(2x - arccos(\frac{1}{2}))(2 - (\frac{-(0)}{((1 - (\frac{1}{2})^{2})^{\frac{1}{2}})}))\\=&-10sin(2x - arccos(\frac{1}{2}))\\ \end{split}\end{equation} \]
