\sin(90+60)=\sin(90)\cos(60)+\sin(60)\cos(90)
Whakamahia \sin(x+y)=\sin(x)\cos(y)+\sin(y)\cos(x) ina x=90 me te y=60 kia whiwhi i te hua.
1\cos(60)+\sin(60)\cos(90)
Tīkina te uara \sin(90) mai i te ripanga uara pākoki.
1\times \frac{1}{2}+\sin(60)\cos(90)
Tīkina te uara \cos(60) mai i te ripanga uara pākoki.
1\times \frac{1}{2}+\frac{\sqrt{3}}{2}\cos(90)
Tīkina te uara \sin(60) mai i te ripanga uara pākoki.
1\times \frac{1}{2}+\frac{\sqrt{3}}{2}\times 0
