Euler’s Pi Prime Product  and Riemann’s Zeta Function
 
15:23
What has pi to do with the prime numbers, how can you calculate pi from the licence plate numbers you encounter on your way to work, and what does all this have to do with Riemann's zeta function and the most important unsolved problem in math? Well, Euler knew most of the answers, long before Riemann was born. I got this week's pi t-shirt from here: https://shirt.woot.com/offers/beautiful-pi As usual thank you very much to Marty and Danil for their feedback on an earlier version of this video and Michael (Franklin) for his help with recording this video.. Here are a few interesting references to check out if you can handle more maths: J.E. Nymann, On the probability that k positive integers are relatively prime, Journal of number theory 4, 469--473 (1972) http://www.sciencedirect.com/science/article/pii/0022314X72900388 (contains a link to a pdf file of the article).

Finding Prime Numbers
 
03:38
If this helps you, please click LIKE and help me too. Thanks! Definition of primes. 1 is NOT prime. Use the Sieve of Eratosthenes to find primes up to 50 Teachers: this is a great primer for kids doing the Sieve for themselves - students often find written instructions for this confusing. Show them sieving the multiples up to and including 5 and they should find it a breeze! Get them to stop when they hit 50, then finish the film and they can check their work. Segue - D.I.Y on paper up to 100. They must keep this work to help them remember. They will eventually learn the first primes for themselves, but it's much better to work it out and be able to look back and review it rather than trying to cram it by rote.

Math Mornings at Yale: The Patterns in the Primes, with Andrew Granville
 
01:00:15
Math Mornings is a series of public lectures aimed at bringing the joy and variety of mathematics to students and their families. Speakers from Yale and elsewhere talk about aspects of mathematics that they find fascinating or useful. The talks will usually be accessible to students from 7th grade and up, although occasionally some familiarity with high-school subjects will be helpful. Math Mornings lectures will take place on three Sundays each semester, at Davies Auditorium, 10 Hillhouse Avenue. Math Mornings is partially funded by grants from the National Science Foundation. It is part of Yale's Science Outreach program. To find out more see http://yale.edu/scienceoutreach On Sunday, March 30, Andrew Granville gave his talk, "The Patterns in the Primes." A whole number, greater than 1, is a prime number if, and only if, it is not the product of two smaller whole numbers. The sequence of primes begins 2, 3, 5, 7, 11, 13, ... Are there any predictable patterns in the prime numbers? Is there are a formula for primes? Perhaps the main difficulty in answering these questions is that primes are defined in terms of what they are not (that is, they are not the product of two smaller whole numbers), rather than what they are, which makes them surprisingly difficult to understand. In this talk, Andrew Granville reviews what is known to be true, what we believe to be true but cannot prove, as well as discusses some wild speculations. He explores some of the latest most exciting discoveries in the theory of prime numbers, and see how we can apply those discoveries.

13:10
Get the full course at: http://www.MathTutorDVD.com In this lesson, the student will learn how to find the prime factors of a number and how to write the prime factorization down. The easiest way to do this is to write down the factors in a "factor tree". The prime factors are the numbers at the "bottom" of the factor tree. Finding factors of a number (number factors) isn't hard. In fact, math factoring is very easy once this simple technique of using a factor tree is understood.

Makes more sense to make a video which describes the problem and the solution, plus its history and the fact a one sentence proof exists... then have a more technical second video for people who want to see the proof itself.

I make math courses to keep you from banging your head against the wall. ;) Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!” So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student—from basic middle school classes to advanced college calculus—figure out what’s going on, understand the important concepts, and pass their classes, once and for all.

Proof: There are Infinitely Many Primes (There is no Largest Prime)
 
04:25
In this math lesson we go over a proof by contradiction that proves there are an infinite amount of primes. It is a very important and interesting result, but it is quite easy to prove! The proof supposes there are finitely many primes then considers the number that is the product of all the primes plus one. From here, using the fundamental theorem of arithmetic, a contradiction follows. Thus, we know that our original assumption is false and there are instead infinitely many primes! Enjoy! I hope you find this video helpful, and be sure to ask any questions down in the comments! ------------------------------------------------------------ Check out my music channel! http://www.youtube.com/seanemusic Check out my blog! https://www.seanemusic.wordpress.com

I show a non-conventional proof that there are an infinite number of primes, which happens to involve the constant Pi. Two of the facts used in this video-- that the zeta function can be rewritten in terms of a product of terms involving prime numbers, and that pi^2/6 = 1 + (1/4) + (1/9) + ...-- are not obvious, and I encourage the viewer to look up proofs of these separately!

Prime is shown through the example of 3 2. Second example given is 8. Not prime, so composite. Defintion of composite number: more than 2 factors 3. Third example is 2, the only even prime number. Every even number has 2 as a factor, so every even number greater than 2 is a composite number.

REAL NUMBERS Ex 1.2 Class 10 - Express 140 as product of its prime factors

Class 10th maths, Real Numbers, Express 140 as product of its prime factors Solution to class x cbse ncert state boards Class 10th Mathematics REAL NUMBERS In class 8th we studied rational numbers and in 9th class we studied real numbers. We also encountered irrational numbers in 9th. In this class we continue our discussion and application of real numbers. Here we deal with two important properties of real numbers namely Euclid’s division algorithm and Fundamental Theorem of Arithmetic. 1: Euclid’s Division Lemma: Given positive integers a and b, there exists unique integers q and r satisfying a = bq + r, 0 is less than or equal to r is less than b. 2: Fundamental Theorem of Arithmetic. Every composite number can be expressed (factorized) as a product of primes and this factorization is unique, apart from the order in which prime factors occur. In this series of video lessons we will: 1. Use Euclid’s division algorithm to find HCF and LCM of numbers. 2. Solve word problems using Euclid’s division algorithm. 3. Express numbers as product of prime factors. 4. Find LCM and HCF using prime factorization method. The only mathematics channel from Jammu and Kashmir.

Here we deal with two important properties of real numbers namely Euclid’s division algorithm and Fundamental Theorem of Arithmetic. 1: Euclid’s Division Lemma : Given positive integers a and b, there exists unique integers q and r satisfying a = bq + r, 0 is less than or equal to r is less than b. 2: Fundamental Theorem of Arithmetic . Every composite number can be expressed (factorized) as a product of primes and this factorization is unique, apart from the order in which prime factors occur. In this series of video lessons we will: 1. Use Euclid’s division algorithm to find HCF and LCM of numbers. 2. Solve word problems using Euclid’s division algorithm. 3. Express numbers as product of prime factors. 4. Find LCM and HCF using prime factorization method. The mathematics channel from Jammu and Kashmir.

Prime Numbers in Microsoft Visual Studio
 
06:28
A prime number (or a prime) is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself. However, 6 is composite because it is the product of two numbers (2 × 3) that are both smaller than 6. Primes are central in number theory because of the fundamental theorem of arithmetic: every natural number greater than 1 is either a prime itself or can be factorized as a product of primes that is unique up to their order.

Prime Numbers are related to this video. A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number. For example, 5 is prime because 1 and 5 are its only positive integer factors, whereas 6 is composite because it has the divisors 2 and 3 in addition to 1 and 6. The fundamental theorem of arithmetic establishes the central role of primes in number theory: any integer greater than 1 can be expressed as a product of primes that is unique up to ordering. The uniqueness in this theorem requires excluding 1 as a prime because one can include arbitrarily many instances of 1 in any factorization, e.g., 3, 1 · 3, 1 · 1 · 3, etc. are all valid factorizations of 3 Video link: https://www.youtube.com/edit?o=U&video_id=kKVDQe413ok prime numbers. factoring. prime factorization. factorization. prime factorization calculator. factor tree. what is prime factorization. what is a prime factor. maths factor. product of prime factors. factor math. prime factor calculator. factors of a number. factorization, factoring, prime numbers, prime factorization, factoring examples, factorization method, prime factor calculator, product of prime factors, factorisation method, factor out, prime calculator, factorization math, prime factorization of 75, prime factorization calculator, math factorization, prime factorization chart, prime factors of a number, the prime factorization, factor numbers, prime factors of 12, prime factorizations, integer factorization, factoring large numbers, find the prime factorization, maths factor, example of prime factorization, factoring terms, finding prime factors, find prime factors, list of prime factors, factors of a number, prime factorization examples, factorization in maths, prime factorization method,
