[net.math] Interesting trig problem

cochon@sun.UUCP (Philippe Lacroute) (12/01/83)

Solve for x:

	x = sin(cos(sin(cos(sin(cos(...(k)))))))

	where k = any number (the k value is irrelevant)
	x always comes out to a constant, seemingly irrational
	number when any k value is tested.  The problem is to
	solve it for an exact value.  The farthest I have gotten
	is this:
		x = sin(cos[sin(cos(...))])

		so x = sin(cos(x))

	I don't know if this is helpful.
