\sin(90+45)=\sin(90)\cos(45)+\sin(45)\cos(90)
Whakamahia \sin(x+y)=\sin(x)\cos(y)+\sin(y)\cos(x) ina x=90 me te y=45 kia whiwhi i te hua.
1\cos(45)+\sin(45)\cos(90)
Tīkina te uara \sin(90) mai i te ripanga uara pākoki.
1\times \frac{\sqrt{2}}{2}+\sin(45)\cos(90)
Tīkina te uara \cos(45) mai i te ripanga uara pākoki.
1\times \frac{\sqrt{2}}{2}+\frac{\sqrt{2}}{2}\cos(90)
Tīkina te uara \sin(45) mai i te ripanga uara pākoki.
1\times \frac{\sqrt{2}}{2}+\frac{\sqrt{2}}{2}\times 0
