Talk:Hudson's equation

Units?
which units are used? without units, the whole equation is without meaning! Gorbalad (talk) 16:33, 12 July 2009 (UTC)

I would assume SI units, since those are the only ones used for any proper science... but then again the equation is the work of US armed forces. 79.138.205.160 (talk) 20:18, 3 December 2009 (UTC)

Cotangent?
Is there any good reason to divide by the cotangent, instead of multiplying by the tangent? I mean, yes they are trivially the same, but for the sake of simplicity both multiplication and avoiding the reciprocal trigonometric function are good ideas. 79.138.205.160 (talk) 20:18, 3 December 2009 (UTC)
