Review for "Solutions of an equation with zero sets (Solutions of the equation $x^y=y^x$)"

Ways to use it unclear.

Review filed on 2010/07/17 14:09 by Christian Mercat.

The only thing I see is the graph of a function on the positive numbers (which one is not clear) and the diagonal. The text suggest it is the positive solutions of x^y=y^x. Zooming on it you can have an approximation of the intersection, around e=2.7182818 where the graphs degenerate to dots. I really don't understand how this curve is computed and I don't see how it can be used in the classroom.
This review is done without a trial in classroom.
