Let A = [ 3 5 7 5 11 4 7 4 1] , write A’ and state whether A is symmetric or skew symmetric matrix Share with your friends Share 0 Vijay Kumar Gupta answered this Dear Student, Consider the following matrix: A=3575114741The Transpose of a matrix A=aijm×n then A'=ajim×nTherefore we have, A'=3575114741Here we noticed that A'=AAlso, by definition, a square matrix A is said to be symmetric if A'=ATherefore, the given matrix A is symmetric matirx. Regards 0 View Full Answer Nidhi Upadhyay answered this A' = [ 3 5 7 5 11 4 (for finding transpose just exchange rows and columns) 7 4 1] since, A'=A therefore A is a symmetric matrix. 1
