Note that there are actually multiple ways to handle infinitely large numbers. 1 decade ago. At first, you may think that infinity divided by infinity equals one. The infinity can somehow branch in a peculiar way, but I will not go any deeper here. This question has been asked before and already has an answer. Exists only to promote a product or service. However, some types of numbers are not well represented by the real numbers. Anything divided by infinity is zero, as well. We can even square the infinity and have ω2. On Qalaxia: Qalaxia will be ready for use in April 2017. 1 3. Section 7-7 : Types of Infinity. We would wind up with: Zero divided by zero is an unknown value. Through articles and podcasts, it explores issues, challenges, and controversies relating to human and artificial intelligence from a perspective that values the unique capabilities of human beings. Students cannot get help for answering questions. How does this help us do math and solve problems? What is 1/ω or ω-1? Once you have an infinite unit like ω, you can do a lot with it. The set-theoretic definition of infinity. Therefore, for the given fraction, we can say, for all practical purposes, when x = 5, the result is 10. In actuality, when any number (including zero) is multiplied with infinity, then the results are always undefined. We can add one to it and have ω + 1. Mind Matters is published by the Walter Bradley Center for Natural and Artificial Intelligence. The real numbers don’t handle numbers that are infinitely large or their inverses—numbers that are infinitely small. However, with the real numbers, we would have to modify x a small, finite amount to get an answer. We don’t have to know which one, we just have to agree that it won’t change. Students love Qalaxia as they earn rewards for providing correct answers to quiz questions and for posting good questions for experts to answer. 4. What does Infinity Divided by Infinity Equal? At most, the real numbers are extended with the positive infinity (∞ or + ∞) or negative infinity (- ∞) symbols to denote numbers too large or too small for the system to handle. These are all hyperreal numbers. Section 7-7 : Types of Infinity. Please sign-up here for updates. Is infinity the reciprocal of zero/is zero the reciprocal of infinity? We can multiply infinity by two and have 2 ω. Qalaxia encourages students to gain knowledge not just from teachers, but also from remote industry expert volunteers. Any number multiply by infinity is infinity or indeterminate. These are all hyperreal numbers. Qalaxia is a question-and-answer platform built to nurture the inquirer, seeker and explorer in every student.

You should think of ω as a kind of unit but, instead of representing a physical quantity (like a foot or a mile or a kilogram), it represents a numerical quantity that is an infinity. This can be rewritten as: 0 * ∞ = c . If we calculate the value at 5 + ε, the calculation will work out to: So, the result of this is 10 + ε, which is infinitely close to the number 10. Source(s): college math courses. So what is ω, exactly? This can be rewritten as: 0 * ∞ = c. So, zero times infinity is an undefined real number. Therefore, zero times infinity is undefined. After all, any number divided by itself is equal to one, however infinity is not a real or rational number. To be explicit, you can use the “standard part” function std to “round” the value to the nearest real number. What would we get? Most of us learned the basic number systems in high school—integers (positive and negative whole numbers), fractions (ratios of numbers), real numbers (all those infinitely-continuing decimals), and maybe even complex numbers (with the evil letter “i” lurking around and causing trouble). Because the hyperreals are new, there is no universal standard for what the notation for infinity should be, so I usually adopt a lowercase Greek omega (ω). A tutorial on Chaitin’s number (Robert J. However, that will be inexact because we could always choose a value a little closer to 5. Signing up means you are OK with Qalaxia's Terms of Service and Privacy Policy. Can Blockchain Help Ensure Fraud Free Voting? Lain Lain. As it turns out, the particular infinity it refers to doesn’t really matter, provided that we are consistent about it. Just as we pictured ω as a 1 with an infinite number of zeroes after it, you can picture ε as a decimal looking like 0.0000001, except that there is an infinite number of zeroes between the decimal place and the 1. As a simple example, let’s say we have the following equation: Let’s say that we wanted to find out what the value of this equation was at x = 5. infinity over infinity and zero multiplied infinity in a calculation which gives (correctly) 1. What does Infinity Divided by Infinity Equal? As we will see, there are many different infinities. Students can get for help for answering homework questions. Watch Queue Queue Natural and Artificial Intelligence News and Analysis, Apocalypticism, Dystopia, and the Singularity, Applied Intelligence, Problem Solving, and Innovation, Bingecast: Enrique Blair on Quantum Computing, George Gilder on Blockchain and Carbon Computing, Artificial Intelligence Gaming the Stock Market. A set of questions with explanations that students can revisit multiple times for review.
