Solve the problem.Graph y = cos 2x and y = sec 2x together for - 
? x ? 
. Comment on the behavior of sec 2x in relation to the signs and values of cos 2x.
What will be an ideal response?
When y = cos 2x is at a maximum point, which is at any multiple of ?, y = sec 2x is a minimum point. Similarly, when cos (2x) is at a minimum point, which is at any odd multiple of 
, y = sec 2x is a at maximum point.
