On a unit circle, sin x = square root 3 over 2, with center O.

Vertical line from top to center of circle is PO.

Horizontal line from middle to right of circle is OE.

Another vertical line of AB is parallel to PO.

And radius of circle (line from O to A) is 1 unit.

From A to E is the arc.

From E to B is another arc.

) is the angle 60 degree

Fine the area of the shaded region (where the ::::: are).

Sorry it's a bad diagram, can't really draw a circle on here..
