Show that for any differentiable function g(τ), u(x, z, t) = g(t − px − ηz), where p is a constant and η = /v 2 − p2, satisfies the 2d wave equation ∂2u+∂2u= 1 ∂2u. ∂x2 ∂z2 v2 ∂t2 also show that u(x, z, t) is a plane wave traveling at a horizontal (x-direction) slowness of p.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

grab rope, tie a loop-de-loop, put it around ur neck, now jump while its tied to a high place. now your shoes are cool.
