The first thought I came up with is to exploit the powerful ...

First, inline free form input can solve these equations:
But it seems no native Mathematica function can solve these, there is even an error page for equations of this form (nestdv).
Now my ...

How does WolframAlpha do this:
I'm aware of services such as RIES, which is an inverse equation solver, and ISC, the Inverse Symbolic Calculator. But WA goes much further.
