Solve Problem in 0 <= x <= 2pie

[hollerback1]

Hi I don't know how to start this problem off...

Solve for 0 <= x <= 2pie

2sec^2x + tan^2x = 3

hmmmmm... sorry if the setup is confusing, the ^2 is supposed to mean squared, thanks.

Solve for 0 <= x <= 2pie<------What kind of pie?. Cherry?. Lemon?. You're not really that obtuse, are you?. You're just being wacky?. Right?.

2sec^2x + tan^2x = 3

hmmmmm... sorry if the setup is confusing, the ^2 is supposed to mean squared, thanks.

big hint ...

sec²x = 1 + tan²x
