$\map \sin {a + b} = \sin a \cos b + \cos a \sin b$

$\map \cos {a + b} = \cos a \cos b - \sin a \sin b$

$\map \tan {a + b} = \dfrac {\tan a + \tan b} {1 - \tan a \tan b}$

$\map \sin {a - b} = \sin a \cos b - \cos a \sin b$

$\map \cos {a - b} = \cos a \cos b + \sin a \sin b$

$\map \tan {a - b} = \dfrac {\tan a - \tan b} {1 + \tan a \tan b}$
