Rewrite each of the following expressions in terms of either sin$(θ)$ or cos$(θ)$. Homework Help ✎

1. tan$(θ)$

$\text{Remember, sin(\textit{x}) = }\frac{\text{opposite}}{\text{hypotenuse}}$

$\text{cos}(x)\ =\ \frac{\text{adjacent}}{\text{hypotenuse}}$

$\text{tan}(x)\ =\ \frac{\text{opposite}}{\text{adjacent}}$

2. csc$(θ)$

This is the reciprocal of sin$(θ)$.

3. cot$(θ)$

This is the reciprocal of tan$(θ)$.

4. sec$(θ)$

What is sec$(θ)$ the reciprocal of?
