I'm confused regarding why the double modulus sign is used. Let's take the dot product:(adsbygoogle = window.adsbygoogle || []).push({});

u.v=|u||v|cosθ The R>H>S means that the cosine of the angle is multiplied witht the magnitudes of both vectors.

Now,

u.v=||u||||v||cosθ

Does this mean the same thing? Help?
