How to prove a matrix is invertible
If A is invertible it is full rank · Rank(A) + Nullity(A) = dim A · The null space is the set of vectors x s.t. Ax=0. · Using Rank(A) + 0 = dim A means Rank(A) = ... ,So A−1 exists, hence A is invertible. Note: if you had the value of A you would only calculate its determinant and check if it is ...
