Re: How to square a vector..

There are three different kinds of "multiplication" defined for vectors: scalar multiplication, the dot product, and, for three dimensional vectors, the cross product.

1) Scalar multipication involves a scalar and a vector so there cannot be a "square".

2) The dot product gives a scalar result: <v1, v2, v3>.<u1, u2, u3>= v1u1+ v2u2+ v3u3 so that the square would be <v1, v2, v3>^2= v1^2+ v2^2+ v3^2 a scalar (number) not a vector.

3) The cross product of two vectors is a vector but it is "anti-commutative" so that the "square", the cross product of a vector with itself is always the 0 vector.

Perhaps a special kind of "vector multiplication" is being defined but your link does not work.

Thanks for the reply!

I know that vectors have a dot product. But with the equation above, i just couldn't make sense of it.

By "link not working", do you mean the image attachment is not visible?

Try this link: http://i50.tinypic.com/n5oc2g.jpg

I'll check my results by getting the dot product again.. And see if I've made any mistakes.

Re: How to square a vector..

The dot product seems to be producing relatively accurate results.

I guess theres nothing else to be done here =]

Thanks again @HallsofIvy
