If you had calculated the displacement vectors in the opposite manner (by subtracting from(0, 3, 0) ) would it have affected the answer?

A good answer might be:

No--both vectors would point in the opposite direction, but the dot product would be the same.

This chapter did little but work with the formula for the cosine of the angle between two vectors. Only a few topics may need reviewing:

  • angleFormula The formula for the cosine of the angle between unit vectors.
  • stepList List of steps to take in applying it.
