Motivating example
It would be nice if the motivaitng example could be made a little more concrete for those of us for whom vector spaces aren't second nature. In particular, the "terms u and f" seem to be free variables and this layman, who doesn't know what the required linear transformation should be, can't think of any meaning for them!

See page
In a couple of places there is a parenthetical referring to what I assume is a page number, i.e. "(see 350)". What do they refer to and can that information be included in the page? Ghartshaw (discuss • contribs) 20:38, 18 April 2017 (UTC)
