1. The problem statement, all variables and given/known data

tan2x+cos2x+sin2x=sec2x

*the 2 stands for squared since I dont know how to make the squared symbol appear on a compter

2. Relevant equations

stuff from this website and more

3. The attempt at a solution

(sin2x+cos2x(cos2x)+sin2xcos2x)/cos2x

1+cos2x+sin2xcos2x/cos2x

1+sin2xcos2x

any help is appreciated as I have been at this for over an hour and cant figure it out and it needs to be done soon
