Evaluate sec 240á without using a calculator by using ratios in a reference triangle.

60=pi/3
cos 60 = 0.5
sec 240 = 1/ cos 240
 cos 240 = cos (180+60)
cos (180+x) = -cos x
cos (180+x) = -cos x
so
cos 240 = -cos 60
              = -0.5
sec 240 =1/ cos 240
              = 1/(-0.5)
              = -2
