Lösung 4.4:6c
Aus Online Mathematik Brückenkurs 1
If we use the trigonometric relation \displaystyle \sin (-x) = -\sin x, the equation can be rewritten as
In exercise 4.4:5a, we saw that an equality of the type
is satisfied if
where n is an arbitrary integer. The consequence of this is that the solutions to the equation satisfy
i.e.
The solutions to the equation are thus
where n is an arbitrary integer.
