		An Exercise in Indefinite Iteration

Assume  f(x)  is a function that is negative in some finite interval that is a
subset of 0≤x≤1.  Design an algorithm to find an  x  for which  f(x)  is
negative; it should work in principle even if the interval is extremely small.

Demonstrate your algorithm by writing a program which makes
	f(x)=COS(505.60213*x)+COS(386.16855*x)+1.999 
negative.

I suggest debugging your program using a function for which you know the answer,
like
	f(x)=SQR(x-0.29)-0.001

This program requires no calculus; the body can be written in under thirty lines.
