Answer:) We see that the three vectors making up A, which are
are linearly independent (since
, which means they are non-coplanar, and hence independent in 3D),
we can form an orthonormal basis out of them:
Now, we get that :

Please Urgent help me!!!(QR decomposition
queastion)
You have not to solve all parts of
question!!!
The QR decomposition can be used to solve a linear system. Let A be an n x n matrix, with A system Axb can be written as QR. Then, the linear QRx = b The process goes as follows Solve Qy b for y Solve Rx-y for x a. It is very easy to solve for y without using Gaussian elimination. Why? b. The solution...
