This notation of yours appears rather mixed up. This hints at

possible deeper misunderstandings. The way you wrote it, x, y and z

are individual coordinates, yet you're willing to specify a normal

vector by a single letter: 'n' --- so why not just call that vector

'P' or 'X' instead?

Or is 'n' not meant to be a vector? If so, what is it?

"The" rotation? What rotation? There's no rotation parameter

mentioned anywhere to be seen.

And what "point"? Was (x,y,z) supposed to be a point, not a vector,

after all?

Maybe you should take a few mental steps back to territory where

you're sure what the words mean, and explain this again, using those

words.
