What is the benefit of using unit vectors rather than not using them??(adsbygoogle = window.adsbygoogle || []).push({});

I am not seeing the point of them? It seems to me that you can do the same calcs without adding the ihat and jhat.

Can someone explain exacly how and why unit vectors make vector calcs easier, or why we need them. Thanks

I do understand what a unit vector is, but i dont understand how they simplify calculations??
