How to Identify If the Given Matrix is Singular or Nonsingular

A matrix is singular iff it has eigen value.A) one.B) two.C... | Filo

Prove that if A^2=A, then either A=I or A is singular Getting Started: You must show that either A is singular or A equals the identity matrix. (i) Begin your proof by observing that A is either singular or nonsingular. (ii) If A is singular, then you are done. (iii) If A is nonsingular, then use the inverse matrix A^-1 and the hypothesis A^2=A to show that A=I | Numerade
