Ответ:
Vectors , and are linearly independent.
Step-by-step explanation:
From Linear Algebra, we must remember that a set of vectors is linearly independent if and only if coefficients of its linear combinations are all zeroes. That is:
, where . (Eq. 1)
Where:
- i-th Polynomial of the set of vectors, dimensionless.
- i-th coefficient associated with the i-ith polynomial of the set of vectors, dimensionless.
Let , and elements of the set of vectors, whose linear combination is:
Values of coefficient are contained in the following homogeneous system of linear equations:
(Eq. 2)
(Eq. 3)
(Eq. 4)
The solution of this system is:
, ,
Which means that given set of vectors are linearly independent.
