These identities mostly refer to one angle denoted θ, but there are some that involve two angles, and for those, the two angles are denoted α and β. Lista över trigonometriska identiteter är en lista av ekvationer som involverar trigonometriska funktioner och som är sanna för varje enskilt värde av de förekommande variablerna. De skiljer sig från triangelidentiteter, vilka är identiteter som potentiellt involverar vinklar, men även omfattar sidolängder eller andra längder i en triangel. Endast de förstnämnda behandlas i denna artikel. Identiteterna är användbara när uttryck som involverar trigonometriska Prove (cos2x)/ ( (cosx + sinx) )= cosx - sinx - Trigonometric Identities - Symbolab.
