Find the Value Using the Unit Circle sin(pi/6)
Problem
Solution
Identify the angle on the unit circle. The angle
π/6 radians is equivalent to30 Locate the coordinates
(x,y) atπ/6 on the unit circle. The coordinates are(√(,3)/2,1/2) Apply the definition of the sine function on the unit circle. The value of
sin(θ) corresponds to they coordinate of the point.Extract the
y coordinate from the point(√(,3)/2,1/2)
