1.If A=[cosα−sinα0sinαcosα0001]A = \begin{bmatrix}\cos\alpha&-\sin\alpha&0\\\sin\alpha&\cos\alpha&0\\0&0&1\end{bmatrix}A=cosαsinα0−sinαcosα0001, then (Adj A)−1=(\text{Adj }A)^{-1} =(Adj A)−1=a.A+IA+IA+Ib.A−IA-IA−Ic.AAAd.Adj(A−1)\text{Adj}(A^{-1})Adj(A−1)Login to continueOnly logged in users canattempt or see the solution.
