Thanks for replying
It doesn't actually v(t) in terms of r(t) or a(t) in terms of v(t). I'm meant to show that it's true for all simple harmonic oscillators
[Note from mentor: this thread was originally posted in a non-homework forum, therefore it does not use the homework template.]

So I've been asked to prove that in a harmonic function where
a(t)+w2r(t)=0
that
(1) v(t).v(t)+w2r(t).r(t)=constant scalar
and...
