Rational Approximation
If 
is any number and 
is any Integer, then there is a Rational Number 
for which
 | (1) |
is Irrational and 
is any Whole Number, there is a Fraction with
and for which | (2) |
for which | (3) |
 | (4) |
if 
, but if 
, thereare some for which this approximation holds for only finitely many .- C*-Algebra
