Can someone(s) explain vectors from begining to end. Elaborate as much as possible. Thanks alot guys ex. using a2 +b2= c2 in vectors

I believe this question is a bit too broad to be answered in an online forum. You might consider a textbook!

vectors are entities that have length and direction, that is all there is to it.

If you add two vectors (as in a2 + b2 = c2) you just add the directions and lengths, so that the result is a vector with a length and direction that is the sum of the two vectors that you have added.

just learn what length and direction mean, and all will be clear...

A vector is a directed line segment. I assume you know what a line is right? Take part of the line and to that add a direction so as to give it a direction. That is a vector.

For details please see - http://mathworld.wolfram.com/Vector.html

Electric field is an example of a vector.

You could say "Well this electric field has a magnitude of x" but in order to fully describe it you must also state the direction in which it acts

Hi, confederateraider!
It's just impossible to teach you vectors through internet. The problem is that I'd be stay here(in front of computer) all day. Sorry, but I think you're "very" accomodated. You can look for textbooks in librarys. I'm sure that you'll find it.

You sound quite motivated.

Dig around the library for some textbooks and see what good stuff you can find. What you may also what to do is ask a math teacher you know and see what they can recommend to you.
