Superposition Principle of Linear Algebra

Superposition Principle

If \mathbf{u} is a solution to \bf{A}\mathbf{x}=\mathbf{b}, and \mathbf{v} is a solution to \bf{A}\mathbf{x}=\mathbf{c}, then \mathbf{u}+\mathbf{v} is a solution to \bf{A}\mathbf{x}=\mathbf{b}+\mathbf{c}.


Properties of Matrix Transpose

1) (A^T)^T=A
2) (A+B)^T=A^T+B^T
3) (kA)^T=kA^T
4) (AB)^T=B^T A^T
