11π/6 = 330°.
On the unit circle the point is (cos, sin) = (√3/2, −1/2). It lies in quadrant IV and has reference angle π/6.
Exact trig values:
- sin(11π/6) = −1/2
- cos(11π/6) = √3/2
- tan(11π/6) = −1/√3 = −√3/3
- csc(11π/6) = −2
- sec(11π/6) = 2/√3 = 2√3/3
- cot(11π/6) = −√3
General coterminal angles: 11π/6 + 2kπ, k ∈ Z.
