Linearly dependent vectors are vectors that can be expressed as a linear combination of each other, meaning one vector can be written as a scalar multiple of another. On the other hand, linearly independent vectors are vectors that cannot be written as a linear combination of each other, meaning no vector can be expressed as a scalar multiple of another. In simpler terms, linearly dependent vectors are redundant and do not add new information to a set of vectors, while linearly independent vectors are essential and provide unique information. **

Linearly independent vectors are a set of vectors where none of the vectors can be written as a linear combination of the others. In other words, no vector in the set can be expressed as a scalar multiple of another vector in the set. If a set of vectors is linearly independent, then the coefficients of the linear combination that equals zero must all be zero. This property is important in linear algebra as it allows for unique solutions to systems of linear equations. **

Linearly independent refers to a set of vectors in a vector space that cannot be written as a linear combination of each other. In other words, no vector in the set can be expressed as a sum of the other vectors multiplied by scalars. If a set of vectors is linearly independent, it means that each vector in the set contributes unique information or direction to the space. **

Vectors are linearly independent when none of them can be written as a linear combination of the others. In other words, if we have a set of vectors {v1, v2, ..., vn}, they are linearly independent if the only solution to the equation c1v1 + c2v2 + ... + cnvn = 0 is when all the coefficients c1, c2, ..., cn are zero. If there exists a non-trivial solution to this equation, then the vectors are linearly dependent. **

To determine if a set of matrices is linearly independent, we need to check if the only solution to the equation c1A + c2B + c3C + ... = 0 is when c1 = c2 = c3 = ... = 0. If this is the case, then the matrices are linearly independent. If there exist non-zero values for c1, c2, c3, ... that satisfy the equation, then the matrices are linearly dependent. **

To determine if a set of vectors is linearly independent, we can form a linear combination of the vectors and set it equal to the zero vector. If the only solution to this equation is the trivial solution (where all coefficients are zero), then the vectors are linearly independent. If there are non-trivial solutions, then the vectors are linearly dependent. **

No, linearly independent vectors are not always orthogonal. Linear independence means that no vector in the set can be written as a linear combination of the others, while orthogonality means that the vectors are perpendicular to each other. It is possible for linearly independent vectors to be orthogonal, but it is not a guarantee. For example, in three-dimensional space, the vectors (1, 0, 0), (0, 1, 0), and (0, 0, 1) are linearly independent and orthogonal, but the vectors (1, 1, 0) and (0, 1, 1) are linearly independent but not orthogonal. **

The vectors [1, 2, 3] and [2, 4, 6] are linearly dependent because one is a scalar multiple of the other. Specifically, [2, 4, 6] is equal to 2 times [1, 2, 3]. Therefore, these two vectors are linearly dependent. **
