then
a' = a * cos(θ) + b * sin(θ);
b' = b * cos(θ) - a * sin(θ);

where θ(shift)...

## Help needed

Posted Jan30-12 at 09:24 AM by xangel25125x

I had a horrible nightmare about a guy named Jimmy that beat me up and raped me in a house and town that made no sense to me. I do not know a Jimmy and I have no clue what this Jimmy even looks like.
