Some have repeatedly questioned the providing of completely worked out solutions, claiming that it's bad pedagogy. Here's a reply.
In the thread Re: Limit n^(1/n) = ? when n approaches +infinite one of the posters wrote (referring to a completely worked out solution):

Of dubious pedagogical value? Many disagree. Please read my ideas about student solutions manuals in the first two threads below, the second containing my reply to some arguments against them. And it destroys motivation? Again, many disagree. Please read below my ideas on how to transfer to the classroom what psychologists know about the workplace regarding creating happy, productive workers.
Are student solutions manuals an answer to the math education problem?
In the context of a strict, unyielding guided discovery method, there are many, many students who are trying as hard as they can, yet they still struggle. And then they fail because they are never given the help they need, completely worked out solutions in a sufficient number of well-designed examples. And then they lose their motivation to continue to try to learn.
