Let's calculate: $\sin \left(\frac{\pi }{6}\right)$

ⓘ The sine is the y-coordinate (vertical axis) of the point reached on the unit circle after a rotation of $\frac{\pi }{6}$ radians from the horizontal axis pointing to the right, this is a remarkable value: $\sin \left(\frac{\pi }{6}\right)$ = $\frac{1}{2}$

▶Result:   $\frac{1}{2}$

The numeric value of: $\frac{1}{2}$ equals:

▷ $0.5$
