FUNCIONES DE LA SUMA DE TRES ARCOS





\begin{array}{r}   \sin(a+b+c)=\sin a.\cos b.\cos c-\sin a.\sin b.\sin c\\   +\sin b.\cos a.\cos c+\sin a.\cos b.\cos c   \end{array}

\begin{array}{r}   \cos(a+b+c)=\cos a.\cos b.\cos c-\sin b.\sin c.\cos a\\  +\sin a.\sin c.\cos b+\sin a.\sin b.\cos c  \end{array}

\tan(a+b+c)=\dfrac{\tan a+\tan b+\tan c-\tan a.\tan b.\tan c}{1-\tan a.\tan b-\tan a.\tan c-\tan b.\tan c}
