2D vector to 3D vector

Question

Hi guys

I'm trying to make a circle across a plane using sin and cos. While it works all well when its aligned with the x, y, or z axis, I need something more dynamic. Is there any way to transform a 2D vector to a 3D one using a plane normal, or perhaps another solution?

Thanks in advanced.
