A = 1/2 * [(A - B^T) + (A + B^T)]
austere charm
A = 1/2 * [(A - B^T) + (A + B^T)]
wait what?
i didnt understand
what you just did
bronze karma
But you understand why they are equal, don't you?
austere charm
what are equal?
bronze karma
A and 1/2 * [(A - B^T) + (A + B^T)]
austere charm
its A^T + B not A + B^T
bronze karma
A and B^T are matrices with the same numbers of rows and columns, evident by the given expression A-B^T
bronze karma
its A^T + B not A + B^T
They are just transposes of each other
bronze karma
A = 1/2 * [(A - B^T) + (A + B^T)]

oh ok

Then assuming the statement is true for some positive integer k
The left hand side of the equation for case k+1 is just one term more than s_k
The right hand side of that is also just some minor modification away from s_k
austere charm
oh ok
