Vector Spaces | Definition & Examples

Vectors in R^n obey a list of rules, things like commutivity of vector addition that a+b = b+a as vectors. However, we can abstract this list of rules and introduce the general concept of a vector space. A vector space has elements that might be all kinds of weird things, but as long as they obey the same list of rules, they are a vector space. And the key here is that all the things we have done in linear algebra extend to this new situation too! Our first new example is polynomial of degree less than or equal 2, which have a natural "vector" addition and scalar multiplication.

Learning mathematics is best done by actually DOING mathematics. A video like this can only ever be a starting point. I might show you the basic ideas, definitions, formulas, and examples, but to truly master math means that you have to spend time - a lot of time! - sitting down and trying problems yourself, asking questions, and thinking about mathematics. So before you go on to the next video, pause and go THINK.
