Exercise 4.3.3 solution
| \( x\) | \( 2\pi\) | \( \dfrac{9\pi}{4}\) | \( \dfrac{5\pi}{2}\) | \( \dfrac{11\pi}{4}\) | \( 3\pi\) | \( \dfrac{13\pi}{4}\) | \( \dfrac{7\pi}{2}\) | \( \dfrac{15\pi}{4}\) | \( 4\pi\) |
| \( \sin x\) | \( 0\) | \( \dfrac{\sqrt{2}}{2}\) | \( 1\) | \( \dfrac{\sqrt{2}}{2}\) | \( 0\) | \( -\dfrac{\sqrt{2}}{2}\) | \( -1\) | \( -\dfrac{\sqrt{2}}{2}\) | \( 0\) |
