Get step-by-step solutions with Wolfram|Alpha Pro?

Questions

One of the advertised features of Wolfram Alpha Pro is that it gives access to step-by-step solutions. I’ve just started using Pro, and I can’t seem to get them to show up consistently. For instance, it pops up as an option for this query

Integrate[(5x+1)^2,x]

but not for

Sum[(-1)^m/((2m-1)^2-1),{m,2,infty}]

Sum[(-1)^m/((2m-1)^2-1 - Wolfram|Alpha),%7Bm,2,infty%7D%5D

I guess my question boils down to:

  • When can/does wolfram know how to do step-by-step solutions?
  • When it is possible, how can one get access to them?

Thanks in advance.

I doubt there is anything you can learn beyond whatever already mentioned here: Wolfram|Alpha Pro

  • When can/does wolfram know how to do step-by-step solutions?
  • When it is possible, how can one get access to them?

Just check and see when there is a button saying it and to access click on it? There is an infinity of various types of problems and my guess is they are adding step-by-step on case-to-case basis. The availability type list is kept here:

There is a bunch of blogs from where it is obvious the functionality is being constantly added:

Quoting one:

Wolfram|Alpha Pro has become well known for its ability to show not only the answer to a question, but also the Step-by-step solution to show how to find the answer. Since its first release, we have developed new features and content for Step-by-step solutions. We’ve added hints and the ability to walk through problems one step at a time, and we’ve added support to show multiple methods for solving problems whenever possible.

Thanks. I had seen the list (examples/StepByStepSolutions), but had taken it as non-comprehensive (“a few examples of …”), whereas your phrase “availability type list” sounds comprehensive. Those blog posts definitely help establish the dynamic nature of their applicability.

I guess my contention is that if Wolfram is selling a product, there ought to be somewhere where a customer can find a reasonable guide of when they can expect to be able to use it. If that list is comprehensive, then it fulfills that (though it should be labeled as such).
