Best ResponseYou've already chosen the best response.2sec(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

Best ResponseYou've already chosen the best response.2so sec(11pi/6) = 1/(sqrt(3)/2) = 2/sqrt(3) = 2sqrt(3)/3
