Formula
\(\csc\theta=\dfrac{1}{\sin\theta}=\dfrac{\text{hypotenuse}}{\text{perpendicular}},\quad \sec\theta=\dfrac{1}{\cos\theta}=\dfrac{\text{hypotenuse}}{\text{base}},\quad \cot\theta=\dfrac{1}{\tan\theta}=\dfrac{\text{base}}{\text{perpendicular}}\)
Variables: \(\theta\) = acute angle of a right triangle.
Conditions: Denominators nonzero.
Reciprocal and quotient transformations.
