Senθ = O/H Cosθ = A/H Tgθ = O/A SOH CAH TOA

α + β = 90° <= ângulos complementares (seno de um é igual o cosseno do seu complemento)

*obs: tangentes de ângulos complementares são inversas

30° 45° 60°

Sen 1/2 √2/2 √3/2

Cos √3/2 √2/2 1/2

Tg √3/2 1 √3

Relação Fundamental: sin^2(X) + cos^2(X) = 1

Sec (x) = 1/cos(X) Cossec (x) = 1/sin(x) Cotg (x) = 1/tan(x) = cos(x)/sin(x)

a^2 = b^2 + c^2
