How can you tell if two vectors are collinear?
If one vector is a multiple of the other vector than they are collinear).Let n equal any natural number (1, 2, 3, 4, ...) and vequal a vector with both amagnitudeand a direction.vn = nv (e.g., v3 = 3v)Vn will always be collinear to v, because it is just a multiple of v (the multiple being n)To verify if two vectors are collinear, if you can factor out a multiple, to return to theoriginalvector, than they are collinear.
The meaning of vector?
A vector is an ordered group of numbers. It has some integer size n, that is to say it has n numbers in it. Often it is writen with the arrow brackets like so v=<v1, v2, v3 ... , vn> Because vectors are ordered <2,1> is different from <1,2>. An easy way to see this is to think that you are grocery shopping and the vector tells you how much apples you have as it's first component v1 and telling how much oranges you have in the v2 component. It is clear that 2 apples and 1 orange is different from 1 apple and 2 oranges.
