Verify the identity: sin(θ)tan(θ)+cos(θ)=sec(θ)\sin(\theta)\tan(\theta) + \cos(\theta) = \sec(\theta)sin(θ)tan(θ)+cos(θ)=sec(θ).
True only when tan(θ)>0\tan(\theta) > 0tan(θ)>0
True using quotient and reciprocal identities
False; this simplifies to csc(θ)\csc(\theta)csc(θ)
False; there is no valid identity here
