WebIgor Konovalov. 10 years ago. To find the eigenvalues you have to find a characteristic polynomial P which you then have to set equal to zero. So in this case P is equal to (λ-5) (λ+1). Set this to zero and solve for λ. So you get λ-5=0 which gives λ=5 and λ+1=0 which gives λ= -1. 1 comment. Web28 CHAPTER 2.

WebOur final definition of positive definite is that a matrix A is positive definite if and only if it can be written as A = RTR, where R is a ma trix, possibly rectangular, with independent columns. Note that, using our energy-baseddefinition, it’s easy to prove that if A = RTR then A is positive definite.
