How do you find the unit vector in a given direction?

• Multiply the vector by its magnitude

• Divide the vector by its magnitude

• Subtract the vector from its magnitude

• Add the vector to its magnitude

What is the purpose of using a dot product in vector analysis?

• To divide vectors

• To multiply vectors

• To determine the angle between vectors

• To find the sum of vectors

When solving vector equations, what is a common method to find unknowns?
