Ok, I agree that most of math is magic.
But it would be nice if there were a special section for "textbook references" --
It doesn't even have to be built into the site, just a convention perhaps, like:
- Strang, Gilbert. Introduction to Linear Algebra, 4E. Pages 82-85.
- Weisstein, Eric W. Gould and Hsu Matrix Inversion Formula. From MathWorld--A Wolfram Web Resource. http://mathworld.wolfram.com/GouldandHsuMatrixInversionFormula.html
The idea is to provide an answer, yes, but to also put references at the end of each post for readers interested in further explanation.
It isn't to simply turn the site into a bunch of textbook references -- each answer should stand on its own -- but to let people know "where you got it" would be nice!
