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