determine whether the functions are linearly dependant or independent
How do you determine if a function is linearly dependent or independent?
If the functions intersect at only one point, then the system is linearly independent and there is only one solution to the system of equations.
If the functions are the same line, then the system is linearly dependent and there is an infinite number of solutions to the system of equations.How do you determine if a set is linearly independent or dependent?
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 show that the functions are linearly independent?
One more definition: Two functions y 1 and y 2 are said to be linearly independent if neither function is a constant multiple of the other.
For example, the functions y 1 = x 3 and y 2 = 5 x 3 are not linearly independent (they're linearly dependent), since y 2 is clearly a constant multiple of y 1.The linear independence of a set of vectors can be determined by calculating the determinant of a matrix with columns composed of the vectors in the set.
If the determinant is equal to zero, then the set of vectors is linearly dependent.
If the determinant is non-zero, then the set of vectors is linearly independent.
