using a right angled triangle as reference, the trigonometric functions or trigonometric identities are derived:
sinθ=OppositeHypotenuse
secθ=HypotenuseAdjacent
cosθ=AdjacentHypotenuse
tanθ=OppositeAdjacent
cosecθ=HypotenuseOpposite
cotθ=AdjacentOpposite
The Reciprocal Identities are given as:
cosecθ=1sinθ
secθ=1cosθ
cotθ=1tanθ
sinθ=1cosecθ
cosθ=1secθ
tanθ=1cotθ
