Properties of adjoint class 12
Did you know?
WebIn mathematics, the term adjoint applies in several situations. Several of these share a similar formalism: if A is adjoint to B, then there is typically some formula of the type (Ax, … Let A be the 2 x 2 matrix and is given by: Then, the adjoint of this matrix is: Here, A11 = Cofactor of a11 A12 = Cofactor of a12 A21 = Cofactor of a21 A22 = Cofactor of a22 Alternatively, the adj A can also be calculated by interchanging a11 and a22 and by changing signs of a12 and a21. This can be shown as: Learn how … See more It is necessary to find the adjoint of a given matrix to calculate the inverse matrix. This can be done only for square matrices. Click here to understand what a square matrixis. See more The formula for the adjoint of a matrix can be derived using the cofactor and transpose of a matrix. However, it is easy to find the adjugate matrix for a 2 x 2 matrix. Let’s have a … See more Example 1: Solution: Here, a11 = 2, a12 = 3, a21 = 1 and a22= 4. So the cofactors are: A11 = a22= 4 A12 = -a12= -3 A21 = -a21= -1 A22 = a11= 2 Example 2: Solution: Let Cij be the cofactor of the element aijin matrix A. Now, the cofactors … See more Consider a 3 x 3 matrix as: The adjugate of this matrix is given by: Here, The above formula can be expanded as: Alternatively, we can find the … See more
WebMar 30, 2024 · Example 24 If A = [ 8(1&3&3@1&4&3@1&3&4)], then verify that A adj A = A I. Also find A–1. Solving L.H.S A (adj A) First Calculating adj A adj A = [ 8(A_11&A_21&A_31@A_12&A_22&A_32@A_13&A_23&A_33 )] Now, A = [ 8(1&3&3@1&4&3@1&3&4)] M11 = 8(4&3@3&4) = 4(4) – 3(3) = 7 M12 = 8 WebProperties of Transpose conjugate: The transpose conjugate of A is denoted by AΘ. If A = [aij]m × n, then AΘ = [bji]n×m where i.e. the (j, i)th element of AΘ = the conjugate of (i, j)th element of A 1) (Aθ)θ = A 2) (A + B)θ = Aθ + Bθ 3) (kA)θ = Aθ, k being any number 4) (AB)θ = BθAθ Addition of matrices:
