Q

1-Fórmulas de adição de arcos

2-Arcos duplos(2a)

3-(a/2)

A

1- Sen(a+b)=sena.cosb+senb.cosa

Cos(a+b)=cosa.cosb-sena.senb

Tg(a+b)= tga+tgb/1-tga.tgb

2- Sen(2a)= 2sena.cosa

cos(2a)= 1-2sena² ou 2cosa²-1

tg(2a)= 2tga/-1tga²

3- Sen(a/2)= ±√1-cosa/2

Cos(a/2)=±√1+cosa/2

Tg(a/2)=± √1-cosa/1+cosa
