Oh okay! Well, is it alright if you can help to see where I could go with this question! I managed to do the first part of the equation (the proof part) but I can't seem to get the send proof (I've attached my working out anyway, so you could see my attempt)(Original post by tiddlytom)
Yeah, did further maths a few years ago - doesn't guarantee I remember it all!

You rightly get:
X = a(2+t^2)
Y = at(2+t^2)
They both share the common factor a(2+t^2), so this can be pulled outside the square root when working out XY. What's left inside the root is (1+t^2) as desired.
