in the expression: v*r (inverted v) 2/1, how to you do the inverted v?

Can’t find it anywhere?

I think it’s better to ask the same question in the other thread.

This duplicate thread makes things complicated.

It is simple math to.invert something relative to a circle of radius r centered on 0. V is a vector and l the length from center to 0.
