Let \(f(x) = e^x \sin 2x + 10\), for \(0 \leq x \leq 4\).

Part of the graph of \(f\) is given below.

The figure is not to scale.

Shown are an x-intercept at point \(A\), a relative maximum at point \(M\) with \(x = p\), and a relative minimum at point \(N\) with \(x = q\).

1. Write down the x-coordinate of \(A\).

2. Find the value of

   1. \(p\)
   2. \(q\)

3. Find \(\int_p^q f(x)\,dx\).

   Explain why this is not the area of the shaded region.
