Very quick question, but need reply fast. I need help with wave functions, and I'm a complete math moron. The equations are in this format:

y(x,t) = A sin(ωt ± kx) which equals

y(x,t) = A sin( (2π/T) t ± (2π/λ)x )

I need clarification on:
T and λ, or just a bit of info explaining the above equations.

Thanks

I don't know math, but your signature is good enough to make me post and say so. Thanks.

oh, and BUMP

Gaaaah that looks familiar, but I'm going out to the pub now!! Sorry!

Anyone please? I need it for tomorrow and it's very hard to search for on the internet.... a quick quick reply will do.

Much appreciated

They are the periods, I believe.

The top one is a wave equation for travelling waves.

T refers to the period and λ is the wavelength. The varible ω is called the angular frequency which is correctly as you stated 2π/T or 2πf.
