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