we can write an equation of a plane in normal form such as rn=d where n is the normal vector and d is the dot product of a point on the plane and n.
what is the specialty when n is a unit vector?

specialty?
I don't see any...
In fact, I don't see how the length of the normal vector you chooses matters at all o-0

I'm flipping though my calc book, but...

i think i got the point, tnx for your efort
when we use unit normal vector,the d we get  is the distance form origin!

oh yeah, makes sense
thank you :D
