Question 945259
How do I complete the problem sec(x)=2 for 0≤x≤π^2 ?

How do the limits figure into the problem?

I've tried converting it to (1/cos(x)) = 2 and working from there, but it is not working out properly.

My book tells me to use reference triangles, and I feel I have a good grasp on problems such as csc (7π/6) but I am unable to complete this type of problem.
======================
If sec(x) = 2, the cos(x) = 1/2.

I doubt it's pi^2, probably 2pi.
For 0 <= x < 2pi,
x = 60 degs
x = 300 degs
-----------
You can convert to radians.
