Given that sin pie/6 = 1/2, use an equivalent trigonometric expression to show that cos= 1/2. I have no clue how to do this, can someone help me?

If cos x = 1/2 then x = cos^(-1) (1/2) therefore, x = 60 degrees , 300 degrees {where x is greater than or equal to 0 and lesser than or equal to 360} or pi/3 radians, 5pi/3 radians {where x is greater than or equal to 0 and lesser than or equal to 2pi}
