Define orthogonality in your own words.
Think about the angle between the vectors.
What do we call a set of vectors that are all orthogonal and have unit length?
Starts with 'o'.
What does it mean for two vectors to be orthogonal?
Think about the angles between them.
True or False: An orthonormal set can consist of vectors that are not unit vectors.
Recall the definition of orthonormality.
Given the vectors u = (1, 2) and v = (3, 4), determine if they are orthogonal and convert them into an orthonormal set.
Check the inner product first before proceeding to the Gram-Schmidt process.
Explain how deriving an orthonormal set can lead to simplifications in a finite element model for structural analysis.
Think about how calculations are interconnected and reliant on the system of vectors.
