Hi there,
i would like everyone to evaluate my working here,
this is my attempt to wave equation / vibrating system using vector approach.

Thanks, and have a nice day.

Regards,
Daniel.

I didn't know that we can compute the Laplacian of a vector.
$$\nabla^2 \vec{U}$$

i think i got what you mean,
position vector is considered as scalar field as well, isn't it?
it is just a notation of denoting the field.
