When are we interested in one over the other? Obviously, (1) tells us that y is represented in terms of ωt( 2πt/T) and ø. Whereas, (2) produces an equation stating the wave number, k(I tend to look at k as the number of cycles/2π) and if we take 2π/k, we obtain the period, T.

vt gives us the shift/ distance as a function of the speed of the wave and the time over which it travels. vt is also really just ø, isn't it?
