I wonder whether it's the case that for a definition like ##v=f(t)##, that makes ##v## a function as well? Or whether it's a bit of an abuse of notation as to why we can treat ##v## as a function and ignore ##f##.

It's a bit like if we're drawing graphs and we get something like ##z = x + y##, and we might say ##z## is a function of ##x## and ##y##, but we could also move everything to the LHS and define ##F(x,y,z) = z-x-y##, and now ##F## is a function. The two usages appear to be quite different.

I wondered whether anyone could clear some of this up, thank you!
