Find the exact value of sin(23pi/3)
**
Working with degrees:
23π/3=23*60º=1380
1380-3*360=1380-1080=300
reference angle=60º in quadrant IV where sin is negative
sin(23pi/3)=-sin 60º=-√3/2
..
Working with radians:
23π/3=21π/3+2π/3=7π+2π/3
Reference angle=2π/3 in quadrant IV where sin is negative
sin(23pi/3)=-sin (2π/3)=-√3/2
