Looks fine to me. I wonder why you called the 3rd coordinate 'w' instead
of the usual 'z', but otherwise it's very clear. Especially, the
mathematics formula is readable line by line, but can also be easily
converted to the vector-based writing :-)

BTW, it seems that the normal term is "keystone correction" instead of
"keystone shaping" as I wrote. You might want to fix it.
