WebbIf \( a \sin ^{2} \theta+b \cos ^{2} \theta=m, b \sin ^{2} \phi+a \cos ^{2} \phi=n \), \( a \tan \theta=b \tan \phi \), then which of the following is true??... WebbHINT: tan θ = 2 sin θ sin θ = 2 sin θ cos θ sin θ ( 1 − 2 cos θ) = 0. ADDED: I am rewriting this in a form where you can "read off" solutions. a b = 0 a = 0 or b = 0. So in the case at hand, …
