\sin(180+60)=\sin(180)\cos(60)+\sin(60)\cos(180)
Whakamahia \sin(x+y)=\sin(x)\cos(y)+\sin(y)\cos(x) ina x=180 me te y=60 kia whiwhi i te hua.
0\cos(60)+\sin(60)\cos(180)
Tīkina te uara \sin(180) mai i te ripanga uara pākoki.
0\times \frac{1}{2}+\sin(60)\cos(180)
Tīkina te uara \cos(60) mai i te ripanga uara pākoki.
0\times \frac{1}{2}+\frac{\sqrt{3}}{2}\cos(180)
Tīkina te uara \sin(60) mai i te ripanga uara pākoki.
0\times \frac{1}{2}+\frac{\sqrt{3}}{2}\left(-1\right)
