Which of these is the correct identity for tan(θ)\tan(\theta)tan(θ)?
tan(θ)=cos(θ)sin(θ)\tan(\theta) = \frac{\cos(\theta)}{\sin(\theta)}tan(θ)=sin(θ)cos(θ)
tan(θ)=1cos(θ)\tan(\theta) = \frac{1}{\cos(\theta)}tan(θ)=cos(θ)1
tan(θ)=sin(θ)cos(θ)\tan(\theta) = \frac{\sin(\theta)}{\cos(\theta)}tan(θ)=cos(θ)sin(θ)
tan(θ)=sec(θ)\tan(\theta) = \sec(\theta)tan(θ)=sec(θ)
