Best ResponseYou've already chosen the best response.0from the graph of cosx you can see that it repeatedly goes from 1 through 0 to 1. sec x = 1/cosx so i think you can notice that when cosx=0 secx will have a problem. Right?

Best ResponseYou've already chosen the best response.0alright so A and B as well as C and D both have the same shaped wave, so is it the outer lines in the corners we need to look at?

Best ResponseYou've already chosen the best response.0cosx=1 at x=0. So A,B are not correct since there it equals 0 and not 1

Best ResponseYou've already chosen the best response.0Well having it narrowed down helps, how do we determine which of C and D is the correct answer now?
