There are 2 questions in this calculation: for each question, the 4 derivative of x is calculated.
Note that variables are case sensitive.\[ \begin{equation}\begin{split}[1/2]Find\ the\ 4th\ derivative\ of\ function\ sqrt(DD + bb)sin(wx + arctan(\frac{b}{a})) + c\ with\ respect\ to\ x:\\\end{split}\end{equation} \]
