Liníes trigonometriques

Author:
Jaume Salvó
Si centrem un angle a una circumferència de radi =1, podem identificar cada una de les raons trigonomètriques de α amb un segment.
Pots desplaçar el punt A sobre la circumferència per veure com queden modificades les raons trigonomètrique al mofificar l'angle α.
