Sine

$\sin \theta =\frac{Opposite}{Hypotenuse}$

Cosine

$\cos \theta =\frac{Adjacent}{Hypotenuse}$

Tangent

$tan\theta =\frac{Opposite}{Adjacent}$

$$\tan (x)=\frac{\sin (x)}{\cos (x)}$$

---

$\csc \theta =\frac{Hypotenuse}{Opposite}=\frac{1}{\sin \theta }$ $\sec \theta =\frac{Hypotenuse}{Adjacent}=\frac{1}{\cos \theta }$ $\cot \theta =\frac{Adjacent}{Opposite}=\frac{1}{\tan \theta }$
