Finding Positive Integers for Irrational Number Interval

Click For Summary
SUMMARY

The discussion centers on the existence of positive integers p and q such that the expression s = (p√2)/q falls within a specified interval (x, y) for any real numbers x and y where 0 < x < y. Participants highlight the concept of density of rational numbers in the real numbers, which implies that between any two real numbers, there exists a rational number. This property is crucial for demonstrating the existence of such integers p and q for any given interval.

PREREQUISITES
  • Understanding of real numbers and their properties
  • Familiarity with the concept of irrational numbers
  • Knowledge of rational numbers and their density in the reals
  • Basic algebra involving integers and square roots
NEXT STEPS
  • Study the density of rational numbers in real numbers
  • Explore the properties of irrational numbers, specifically √2
  • Investigate integer solutions to equations involving irrational numbers
  • Learn about intervals and their significance in real analysis
USEFUL FOR

Mathematicians, educators, students studying real analysis, and anyone interested in number theory and the properties of irrational numbers.

someome please help me with this problem:
"Any real numbers x and y with 0 < x < y, there exist positive integers p
and q such that the irrational number s =( p√2)/q is in the interval (x; y)."

Do you know that the rationals are dense in the reals?? What does that mean??
