What is anything divided by infinity equal to?

Published in Mathematics 2 mins read

Anything divided by infinity is equal to zero.

When you divide a number by an increasingly large number, the result gets closer and closer to zero. Infinity is the concept of a number that is larger than any real number. Therefore, when you divide any finite number by infinity, the result is infinitesimally small, effectively zero.

Mathematical Representation:

Mathematically, this can be represented as:

lim (x / n) = 0, as n approaches ∞

Where:

  • x is any finite number
  • n is a number approaching infinity
  • lim denotes the limit

Examples:

  • 1 / ∞ = 0
  • 1000 / ∞ = 0
  • -5 / ∞ = 0

Practical Implications:

This concept is vital in various areas of mathematics, physics, and engineering, including:

  • Calculus: Understanding limits is crucial for calculating derivatives and integrals.
  • Physics: In certain physical models, dealing with infinite quantities is essential.
  • Computer Science: In some programming scenarios, representing infinitely small quantities is necessary for calculations.

Important Considerations:

It's important to note that infinity is not a real number but a concept. Dividing by zero is undefined, but dividing by infinity results in zero.
While many calculators, like the TI-Nspire, will evaluate 1/∞ as 0, it's important to understand the underlying mathematical principle.
