Find the inverse of the matrix A = {bmatrix}a+ib &c+id -c + i

Question

Find the inverse of the matrix
$A = [a + ib - c + i d c + i d a - ib]$ , if $a^{2} + b^{2} + c^{2} + d^{2} = 1$

A^{- 1} = [a + ib c + i d - c + i d a - ib]

A^{- 1} = [a - ib c - i d - c - i d a + ib]

A^{- 1} = [- a - ib c - i d - c + i d a - ib]

Text solutionVerified

A = [a + ib - c + i d c + i d a - ib]

and

a^{2} + b^{2} + c^{2} + d^{2} = 1

Inverse of

[a c b d]

\frac{1}{a d - b c} [d - c - b a]

∴ A^{- 1} = [a - ib c - i d - c - i d a + ib]
