comment Asymptotic forms of Bessel function
Since this is one of the examples in the docs for Series under Scope, I would say this question can be closed.

comment Solve PDE with DiracDelta function
I don't think using the delta function is practical here. It's probably better to use the general solution in each domain (left and right half) and match them according to the compatibility conditions implied by the delta function. That should reduce the problem to a set of simultaneous (algebraic, not differential) equations for the integration constants in each interval once you know the general solution as derived in my answer to the linked question.

comment Solve wave equation using DSolve?
(+1) Indeed, Laplace transforms also helped overcome the inability to solve an integro-differential equation here. For more complex boundary conditions it may be necessary to use superpositions of the general solution I obtained from separation of variables.

comment Exporting a 3D plot into a 3D viewing format and axis scaling
@episanty Good point - I think adding a transformation after the fact is certainly equally possible.

@episanty Wouldn't that also squish the axis labels?
