For the matrix A = [1 5 6 7], verify that i) (A+A') is a symmetric ii) A-A' is a skew |CBSE|NCERT

Ap isme 1/2 nahi likhe hai ap formula galat use kiye hai😢😢😢😢

Actually to be noted that every square matrix A can be written as sum of symmetric and skew symmetric I.e., 1/2( A+A’) + 1/2( A-A’). 1/2 is taken just to balance the sum. A+A’ is symmetric and A-A’ is skew symmetric
