WebHalf Angle Formula - Cosine . Using a similar process, with the same substitution of `theta=alpha/2` (so 2θ = α) we subsitute into the identity. cos 2θ = 2cos 2 θ − 1 (see cosine of a double angle). We obtain `cos alpha=2\ cos^2(alpha/2)-1` WebA standard rate turn is defined as a 3° per second turn, which completes a 360° turn in 2 minutes. This is known as a 2-minute turn, or rate one (180°/min). Fast airplanes, or aircraft on certain precision approaches, use a half standard rate ('rate half' in some countries), but the definition of standard rate does not change. four main types of business
