Løs 3t6sin(3t)=0

$$3 t 6 \sin ( 3 t ) = 0$$

Løs for t_6

$$\left\{\begin{matrix}\\t_{6}=0\text{, }&\text{unconditionally}\\t_{6}\in \mathrm{R}\text{, }&\exists n_{1}\in \mathrm{Z}\text{ : }t=\frac{\pi n_{1}}{3}\end{matrix}\right,$$

Vejledning i at løse lineær ligning

Ligningen er nu i standardform.

$$3\sin(3t)t_{6}=0$$

Divider 0 med 3\sin(3t).

$$t_{6}=0$$
