Question

How do you rotate a figure 270 degrees counterclockwise?

Answer 1

Here's a good example of such a figure before and after rotation.

Answer 2

I actually just wanted a formula. The formula was that (x,y) turns into (y, -x). But thanks :)

Answer 3

Yes, I was wondering what exactly you wanted.

Answer 4

It's a little easier to picture something being rotated 90° clockwise.
Do you have an equation for making this graph that gets rotated 270° counter clockwise?
