Re: What is the Matrix T?

Please show some work in all of your problems so that we get the idea you have actually tried them.

Re: What is the Matrix T?

I'll be completely honest, I haven't. I just have no clue what to do.

are you in a class? do you have a textbook?

Re: What is the Matrix T?

Yeah, I'm in the class MAT1341 at the University of Ottawa. I do have a textbook, and I've looked through it trying to find a way to find a solution and so far I've been unsuccessful.

it's a pretty straightforward question if you've covered linear transformations at all.

a 3x3 rotation matrix about say the Z axis, of rotation angle $\theta$ is

$R_{\theta}=\left(\begin{array}{ccc}\cos(\theta) &\sin(\theta) &0 \\ -\sin(\theta)&\cos(\theta) &0\\ 0 &0 &1\end{array}\right)$

that sort of thing must be in your book somewhere.

a shear matrix in the Z direction of shear factor $\lambda$ is

$S_{\lambda}=\left(\begin{array}{ccc}1 &0 &0 \\ 0 &1 &0 \\ 0 &0 &\lambda \end{array}\right)$

again that's got to be in your book.

take another look

Re: What is the Matrix T?

Thanks for the help, I'm trying to find it but once again I can't haha. I'll keep trying I guess.
