\ =\ \cos(16^\circ\ -\ \8^\circ)\ =\ \cos(16^\circ)\cos(8^\circ)\ +\ \sin(16^\circ)\sin(8^\circ))
\ =\ \cos(16^\circ\ +\ \8^\circ)\ =\ \cos(16^\circ)\cos(8^\circ)\ -\ \sin(16^\circ)\sin(8^\circ))
\ -\ \cos(16^\circ)\ =\ \(\cos(16^\circ)\cos(8^\circ)\ +\ \sin(16^\circ)\sin(8^\circ)\)\ -\ \(\cos(16^\circ)\cos(8^\circ)\ -\ \sin(16^\circ)\sin(8^\circ)\))
\sin(8^\circ))
