Step-by-step explanation:
To prove uniqueness,let A=R+S where R is symmetric and S is skew−symmetric ∴ A'=(R+S)'=R'+S'=R−S { ∵ R'=R and S'=−S by Definition of symmetric and skew−symmetric matrices } ∴ 1/2(A+A')=1/2(R+S+R−S)=R=P
1/2(A−A')=1/2(R+S−R+S)=S=Q.
Hence, the representation A=P+Q is unique. Hence, it is proved that every square matrix can be uniquely expressed as a sum of symmetric and skew-symmetric matrix.
