sec ⁡ ( x) = 1 cos ⁡ ( x) \sec (x) = \dfrac {1} {\cos (x)} sec(x)= cos(x)1. Secant, cosecant and cotangent, almost always written as sec, cosec and cot are trigonometric functions like sin, cos and tan. sec x = 1.

Pitagorina trigonometrijska jednakost je jedna od osnovnih trigonometrijskih jednakosti i prikazuje odnos između sinusa i kosinusa: ⁡ + ⁡ = gdje cos 2 θ znači (cos(θ)) 2 i sin 2 θ znači (sin(θ)) 2.. Izraz je u biti izvedenica Pitagorinog poučka i proizilazi iz jednakosti + = koja vrijedi za jediničnu kružnicu.Ova jednadžba može biti Sekans ugla je trigonometrijska funkcija oblika = ⁡ = ⁡,..
