Coda 2 6 8 – one window web development suite. cos(2x) = cos2(x) - sin2(x) = 2 cos2(x) - 1 = 1 - 2 sin2(x)
tan(2x) = 2 tan(x) / (1 - tan2(x))
sin2(x) = 1/2 - 1/2 cos(2x)
cos2(x) = 1/2 + 1/2 cos(2x)
sin x - sin y = 2 sin( (x - y)/2 ) cos( (x + y)/2 )
cos x - cos y = -2 sin( (x-y)/2 ) sin( (x + y)/2 )
