Lösung 4.4:2c
Aus Online Mathematik Brückenkurs 1
There are two angles in the unit circle, \displaystyle x=0 and \displaystyle x=\pi, whose sine has a value of zero.
We get the full solution when we add multiples of \displaystyle 2\pi,
where n is an arbitrary integer.
Note: Because the difference between \displaystyle 0 and \displaystyle \pi is a half turn, the solutions are repeated every half turn and they can be summarized in one expression,
where n is an arbitrary integer.
