Vectors

Explain why it is not possible for Vector a • (Vector b • Vector c) to equal (Vector a • Vector b) • Vector c . (This means that the dot product is not associative.)

1. Homework dumps generally get little help, unless you show how you tried and failed to solve the problem.

I'll do this one, but you can't expect us to do your work. We did it for ourselves already.

the dot product is only defined for two vectors.

(a•b) is a scalar, so (a•b)•c is not even defined.
