WebConclusion. The inverse of A is A-1 only when AA-1 = A-1A = I. To find the inverse of a 2x2 matrix: swap the positions of a and d, put negatives in front of b and c, and divide everything by the determinant (ad-bc). Sometimes there is no inverse at all. WebWhat is the value of A (3I) , where I is the identity matrix of order 3 × 3. Q. Assertion :Statement-1: Determinant of a skew-symmetric matrix of order 3 is zero. Reason: Statement-2: For any matrix A, Det(A) = Det(AT) and Det(−A) = −Det(A) Where Det(A) …

Math Algebra L: R² → R² is a linear map. If the underlying 2 × 2 matrix A has trace 4 and determinant 4, does L have any non-trivial fixed points?¹ Justify your answer. (Hint: a linear map L has non-trivial fixed points if and only if λ = 1 is an eigenvalue of L). L: R² → R² is a linear map.
