Let $f(x) = \cos x + \sqrt{3}\sin x, 0 \le x \le 2\pi$.
The following diagram shows the graph of $f$.
The $y$-intercept is at $(0, 1)$ and intersects $x$-axis at C and D. There is a minimum point at $A(p, q)$ and a maximum point at B.
Based on the above information, answer the questions that follow.
(a)
Write $f'(x)$ in the form of $\lambda\cos(x+\mu)$.
