if sin theta = 2/3 in quadrant 1, find sec theta. HELP!!!
Answered by MathMate
In quadrant 1, both sin and cos are positive.
Therefore for sin(θ)=2/3
cos(θ)=√(1-(2/3)²)
=√(5/9)=√5/3
sec(θ)=3/√5
=3√5/5

Man this stuff is so hard
Answered by MathMate
If you find this difficult for now, back up a chapter and try the exercises to grasp the building blocks first.

With patience and time, you'll master it eventually.
