2 1 Proof

Keep reading below for the solution.

2 1 proof. If you like my videos you can support me a. And cancelling the from both sides gives 1 2. This can be written as step 8. 3 a 2 b 2 ab b 2 3 subtract b 2 from.

She should determine both which number is wrong and why. 1 a b 1 given. Can you find the mistake in the proof. Prove 2 1 using calculus.

Using algebra and a little deception mr. Show your teen the proof. The proof that 2 1. So here s the puzzle.

Then step 3. This is a false proof of why 2 1 using a bit of differential calculus. I know this sounds crazy but if you follow the logic and don t already know the trick i think you ll find that the proof is pretty. Ex 2 1 3 the product of two odd numbers is odd.

Proof that 1 2 see below what you do. Let s begin our journey into the bizarre world of apparently correct yet obviously absurd mathematical proofs by convincing ourselves that 1 1 1. In 1 4 write proofs for the given statements inserting parenthetic remarks to explain the rationale behind each step as in the examples. Clearly this is a mistake.

Or you can watch my video about the problem and its solution. Ex 2 1 1 the sum of two even numbers is even. Ask her to tell you which step is invalid. Ex 2 1 2 the sum of an even number and an odd number is odd.

How to prove that 2 1. 2 a 2 ab 2 multiply both sides by a. If n a 2 b 2 prime q 3 mod 4 q n then q a q b and q 2 n this reduces to a smaller case n q 2 a q 2 b q 2 continued reduction removes primes equal to 3 mod 4 in pairs so any sum of squares solution of n corresponds one to one to a sum of squares solution of n q 2 r p if q is a square or yields a contradiction implying numsq n 0 if q is not a. John hush proves or does he that 1 2 to a class of amazed calculus students.

But every step seemed valid. Can you figure out where the mistake is.
