A set of vectors is said to be linearly dependent if one of the vectors in the set can be defined as a linear combination of the other vectors.
K1X1+K2X2+K3X3=0
X1 = - K2/K1 X2 - K3/K1 X3
and If no vector in the set can be written in this way, then the vectors are said to be linearly independent.
K1X1 + K2X2 + K3X3=0
implies K1=K2=K3=0
Given
X(1,0,0) Y(0,1,0) Z(0,0,1)
K1(1,0,0) +K2(0,1,0) + K3(0,0,1)=(0,0,0)
(K1,0,0) +(0,K2,0) + (0,0,K3)=(0,0,0)
i.e. K1=K2=K3=0
So vectors are linearly independent.
Here Rank =3
So and number of linearly independent. solution = no of variables - Rank of the matrix
= 3-3 =0
So there There is no linearly independent.
zero Solution will be the only solution which is Trivial.
