Given a set of vectors, you can determine if they are linearly independent by writing the vectors as the columns of the matrix A, and solving Ax = 0. If there are any non-zero solutions, then the vectors are linearly dependent. If the only solution is x = 0, then they are linearly independent.
How do you prove an equation is linearly independent?
If at least one of the equations can be described in terms of the other equations, the system is said to be linearly dependent. If there is no way to write at least one equation as a linear combination of the other equations, then the system is linearly independent.
How do you tell if a function is dependent or independent?
If a consistent system has exactly one solution, it is independent . If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line.
How do you prove that two functions are linearly independent?
Given two functions f(x) and g(x) that are differentiable on some interval I. If W(f,g)(x0)≠0 W ( f , g ) ( x 0 ) ≠ 0 for some x0 in I, then f(x) and g(x) are linearly independent on the interval I.16 nov. 2022
