Eigenvalues of 2 by 2
Web10 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 … It's going to be minus 1 times 1, 0, 0, 1, which is just minus 1 there. Minus A. So … And then 0 minus 2-- I'll do that in a different color. 0 minus 2 is minus 2. 0 … WebFinal answer. 5. Compute the eigenvalues and eigenvectors of X = ( 1 −1 2 4) 6. Consider the plane, P, in R3 given by the vector equation: x(s,t) = (1,−1,2)+s(1,0,1)+t(1,−1,0)
