# SOHCAHTOA

SOH CAH TOA helps you remember the definitions of sine, cosine, and tangent based on the sides of a right triangle,

$\sin \theta = \dfrac{\text{opposite}}{\text{hypotenuse}}\qquad$ **S**ine is **O**pposite over **H**ypotenuse (SOH)

$\cos \theta = \dfrac{\text{adjacent}}{\text{hypotenuse}}\qquad$ **C**osine is **A**djacent over **H**ypotenuse (CAH)

$\tan \theta = \dfrac{\text{opposite}}{\text{adjacent}}\quad\qquad$ **T**angent is **O**pposite over **A**djacent (TOA)
