i usually just either change it to its identity 1+tan^2x or you could just type in your calculator 1/cos(2x)

Its the same as 1/cos^2(x) but, what you actually do it (1/cos(x))^2

If your calculator has brackets I would do:
(1/cos(x))^2

so Bracket, 1, fraction, cos(x), bracket, squared.

or find cos(x), store in in ANS, then do 1/ANS^2

I mean it doesn't matter if squared is bracketed or not or just on the bottom because 1^2=1

I've just realized that this thread is a year old! The OP has probably figured it out by now
