Vectors and the Dot Product
The purpose of this assessment is to help you determine whether you have a clear understanding of vectors and dot products.
Answer the following questions to complete this exercise:
- Let v be a vector from initial point P1 = (-11, -12) to terminal point P2 = (2, 5). Write v in terms of i and j.
- Let u = 8i - 6j and v = -5i + 8j. Find the vector u + v.
- Find the unit vector that has the same direction as vector v = -12j.
- Let u = 4i + 2j and v = -5i - 3j. Find the vector u - v.
- Let u = 6i - 3j. Find 3u.
- Let u = 2i + 2j and v = -3i + 7j. Find u x v.
