What I never liked much in books that should provide knowledge.

[Maximilian Hohmann]

Hello!

I would say that anybody who can make any sense of what this book talks about will definitely derive some kind of pleasure from finding the solution himself ;-)

But you are right, for mere mortals who have to read such books because they require them for their work, "hiding" vital information is not helpful at all. And even if they were able to gain some pleasure from it they might simply not have the time to do the maths themselves.
