If they are equal show that M is not invertible. ) Notice that in this case, det(B - tI n)= det(P-1 AP - tI n. (See Problem " Similar matrices have the same eigenvalues ". Use matrix multiplication to draw R'U'T'H', its refl ection image over the line with equation y = –x. to show B is idempotent B 2 = B. Lecture 8.
Show that a and b are similar matrices by finding an invertible matrix
. Best answer. Matrix calculator. 1 answer `A , B ` are two matrices such that `A B ` and `A+ B ` are both defined; show that `A , B ` are square matrices of the same order. Diagonal matrices are the easiest kind of matrices to understand: they just scale the coordinate directions by their diagonal entries. Assume that A and B are similar.
