What is the inverse of a vector?
Ah, another geometric algebra evangelist? I can&#x27;t figure out if GA actually adds anything substantial, or if it merely lets us write some equations in a more succinct fashion. But it certainly looks cool.<p>As to vectors, obviously they have inverses, additive inverses. Since vectors don&#x27;t have multiplication, there is no multiplicative inverse, but if you define new operations on them, well then that operation can have an inverse but that is not really &quot;the inverse of a vector&quot; anymore.
