1. The problem statement, all variables and given/known data
This isn't a homework question, I am having a bit of trouble with some Trig equations. If you are worried that you are answering a homework question please give me the solution to a similar question.
2. Relevant equations
When we have a trig equation like sec2X + tan2X = 6.
I know that sec is equal to 1/cos, and tan is equal to sin/cos, but what do I do with the square? Do I square all the terms or just the denominator?
3. The attempt at a solution
I have tried many times, to many to list here!
Thanks for your help

Hint: is there a Pythagorean identity that relates secant and tangent?
