ITDENTIDADES TRIGONOMETRICAS
SUMA
Sen (α+β)= Senα Cos β + Cos αSen β
Cos (α+ β)= Cosα Cosβ – Sen α Sen β
Tan (α+ β)= (Tanα+Tanβ)/(1-TanαTanβ)
RESTA
Sen (α-β)= Senα Cos β -Cos αSen β
Cos (α- β)= Cosα Cosβ + Sen α Sen β
Tan (α-β)= (Tanα-Tanβ)/(1+TanαTanβ)
MITAD
Tanθ/2 = + - √((-1 cos θ )/(1+cos θ))
Tanθ/2= (Senθ )/(1+cos θ)
Tanθ/2= (1-cos θ )/(Sen θ)
Sen θ/2 = + - √((1-cosθ)/2)
Cos θ/2 = + - √((1+cos θ )/2)
DOBLES
