Integrating 1/cos²(2y)

[tex]\int\frac{1} {cos^2(2y)} dy[/tex]
I've tried u-subbing and integration by parts...and no luck...
It's been a while since Calc 2 and I need some help.
Any help would be great! thx! :)

I don't think you can solve this by u-subsitution or i couldn't think that way because that owuld be too lengthy

Whats the Differential of Tan??
