Question

Which of the following are the solution of the one dimensional wave equation

$y = {x}^{2} + v ^{2} t ^{2}$
$y = 5 \sin(x) \cos(vt)$
$y = 3 \sin(2x) \cos(vt)$

​

Answer 1

Explanation:

$y = {x}^{2} + v ^{2} t ^{2}$

$y = 5 \sin(x) \cos(vt)$

$y = 3 \sin(2x) \cos(vt)$

Answer 2

Explanation:

y=x*2+v*2t*2

I think so.
