sec (11π / 6) is the same as 1 / cos(11π / 6)

sec(11pi/6) = 1/cos(11pi/6) cos(11pi/6) we can see from the graph that cos(2pi  x) = cos(x) cos(11pi/6) = cos(2pi  pi/6) = cos(pi/6) = sqrt(3)/2

so sec(11pi/6) = 1/(sqrt(3)/2) = 2/sqrt(3) = 2sqrt(3)/3

\[1 / \cos(11π / 6) = 1 / \sqrt{3}/2\] \[= 2\sqrt{3}/3\]
