If the two input vectors are unit vectors (vectors with length of 1), the dot product outputs the cosine of the angles formed by those two vectors. If the two input aren't unit vectors, we can still find the cosine of the angle with two methods: |

The dot product of two unit vectors outputs the cosine of the angle between those two vectors. If our two inputs aren't unit vectors, we can find the cosine with two methods: |
