So for this problem, we're given two vectors and we're asked to add them.
00:03
The two vectors look like this.
00:09
So let's remember that there are two ways that we can add vectors.
00:12
First, there's a triangle rule, which states if we have two vectors that are head to tail like this, we have the head to the tail of the other vector, then the resulting vector, the addition of vectors, is equal to the vector formed from the tail of the first vector to the head of the second vector.
00:31
So this b vector would be the addition of those two vectors.
00:36
Then if, for example, we had two vectors placed tail to tail like this, we'll go like this...
