Finding Parallel and Orthogonal Vectors for u and v

Click For Summary
SUMMARY

The discussion focuses on finding two vectors, u1 and u2, from the given vectors u=(26, 6, 21) and v=(−27, −9, −18). Vector u1 must be parallel to v, while vector u2 must be orthogonal to v, satisfying the equation u = u1 + u2. To determine u1, one can use the scalar multiplication of v, and for u2, the orthogonal condition can be established using the dot product, ensuring it equals zero.

PREREQUISITES
  • Understanding of vector operations, specifically parallel and orthogonal vectors
  • Knowledge of scalar multiplication in vector mathematics
  • Familiarity with the dot product and its properties

The Attempt at a Solution



I'm quite lost on this question and not sure how to even start. Can someone explain the question and give me some hints to get started?

Thanks in advance.

Are you sure that there are no relevant equations? What about those defining defining parallel and orthogonal?
 
Drawing a diagram is always great.
 
There aren't any other questions or equations about this. All I know is if their dot product is 0, then its orthogonal, and my book doesn't even mention parallel.
