## AravindG 4 years ago what is equation of a wave how we get it??show derivation

1. anonymous

equation y=acos/sin(wt-/+kx)

2. AravindG

hw we get it?

3. TuringTest

what kind of wave? and you want a derivation without using differential equations I suppose?

4. AravindG

twiddla?

5. TuringTest

um... hold on let me try to prepare a simple answer first, I think I know what you want...

6. AravindG

k

are you looking to get heena's answer, because I can only show $x(t)=A\cos(\sqrt{\frac{k}{m}}t+\theta_o)$but I have to make the assumption that x will be a trig function of time. Otherwise I would have to use Differential equations. So basically I can only prove that $\omega=\sqrt{\frac{k}{m}}$does that help?

The Dirac equation or a Schrodinger equation... They won a Nobel Prize for their wave equations!
