- hi,
- In "Number Theory" Hardy shows that the difference between an
- irrational number and a rational approximation is:
-
- | r - p/q | <= 1/q^2, 0<p<=q, r irrational, p and q integers.
-
- Another interpretation of this is to consider this as the nearest point
- of an approximating grid to a line of irrational slope. I was wondering
- if anyone could tell me where to find any results for curves with non-zero
- curvature. Thanks in advance.
