You're right that linearly independent need not imply orthogonal. To see this, see if you can come up with two vectors which are linearly independent over $\mathbb{R}^{2}$ but have nonzero dot product.

- Proving that orthogonal vectors are linearly independent
We can satisfy the above equalities only if $c_1=c_2=c_3=0$, thus proving that the set of orthogonal vectors are linearly independent.
17 Σεπ 2022 · However you can verify that the set \(\{\vec{u}, \vec{v}\}\) is linearly independent, since you will not get the \(XY\)-plane as the span of a single vector. We can also determine if a set of vectors is linearly independent by examining linear combinations.
A set of vectors is linearly independent if each of them is outside the space spanned by the others. To make the explanation easier, let's just use a set of three vectors in $\mathbb{R}^3$ . The extension to higher dimensions doesn't add much except a bunch of indices.
Orthogonal vectors are linearly independent. A set of n orthogonal vectors in Rn automatically form a basis. Proof: The dot product of a ak||v k||2 linear relation a 1v + +. anv = 0 withv k gives akv ·. k = = 0 so that ak = 0.
In the theory of vector spaces, a set of vectors is said to be linearly independent if there exists no nontrivial linear combination of the vectors that equals the zero vector. If such a linear combination exists, then the vectors are said to be linearly dependent .
17 Σεπ 2022 · Learn two criteria for linear independence. Understand the relationship between linear independence and pivot columns / free variables. Recipe: test if a set of vectors is linearly independent / find an equation of linear dependence. Picture: whether a set of vectors in R2 or R3 is linearly independent or not.
