Question

Please help. Will medal and fan

Answer 1

Simplify \[\sqrt{\frac{ (1-\cos \theta)(1+\cos \theta) }{ \cos ^{2} \theta}}\]

Answer 2

\[\sqrt{\sin \theta}\] \[\pm \sin \Theta\] \[\pm \cos \Theta\] \[\left| \tan \Theta \right|\]

Answer 3

hint: (1-cos theta)(1+cos theta) = 1 - cos^2(theta) = sin^2(theta(

Answer 4

So it'd be A?

Answer 5

nope, try multiplying out (1-cos(theta))(1+cos(theta)) under the radical and converting to sin^2(theta)

remember you've still got cos^2(theta) in the denominator
