1. The problem statement, all variables and given/known data
Hi, 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 sec^{2}X + tan^{2}X = 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 Dominic

Hi Dominic!
tan^{2}x = sin^{2}x/cos^{2}x (and you can also use one of the standard trigonometric identities …
