This ISI MStat 2016 problem is an application of the ideas of tracing the trace and Eigen values of a matrix and using a cute sum of squares identity.
Suppose A is an real symmetric matrix such that
. Show that all the eigenvalues of A are equal to 1.
This problem is from ISI MStat 2016 PSB ( Problem #3)
.
Since, A is a real symmetric matrix, then all the eigen values of the matrix A are real say {}.
