Linear Dependence with Zero Vector: A Simple Solution?

Click For Summary
SUMMARY

A set containing the zero vector is always linearly dependent. This is because the definition of linear dependence states that a set of vectors is linearly dependent if there exist constants, not all zero, such that their linear combination equals the zero vector. In the case of a single vector, the zero vector itself can be represented as a linear combination with the constant being non-zero, thus confirming the dependence.

PREREQUISITES
  • Understanding of linear algebra concepts, specifically linear dependence

I have to prove that a set that has the zero vector is linearly dependent. Can anyone help me out?

As usual a set {x1,x2...} is linearly dependent if you can find constants (not all zero) such that c1*x1+c2*x2+...=0. What happens if there is only one vector? Doesn't that make it easy?
