## How to linear transform 2D Cartesian coo...

Maple

Hi,

I have a function f(x) = x/2 on Cartesian coordinates. I want to rotate the y-axis clockwise and x-axis anticlockwise by the

same (arbitrary, acute) angle (something like the 2nd figure of http://www.ams.org/publicoutreach/feature-column/fcarc-svd),

yet I also want to retain the Cartesian grid and the function f(x) at the background.

Could someone tell me how to do so? Thanks!

2.I don't know how to restrict my domain to Z

Thanks.
