# Find The Error In The Proof That 2=1

## Contents |

But nuts or not, these are **exactly the things we'll be talking** about today.Of course, there will be a trick involved because 1 + 1 is certainly equal to 2…thank goodness!

Square roots of negative numbers[edit] Invalid proofs utilizing powers and roots are often of the following kind: 1 = 1 = ( − 1 ) ( − 1 ) = − Navigation Panel: Go up to Classic Fallacies index Go down to first subsection This is Not the Fallacy Go forward to 1=2: A Proof using Complex Numbers Switch to text-only version http://indywebshop.com/find-the/find-the-error-1-2-3-4-5.php

finally let a and b be equal to 1, which shows that 2 =1. Thus, by induction, N horses are the same colour for any positive integer N. Yes No Sorry, something has gone wrong. multiply both sides by a to obtain a² = ab.

In order to avoid such fallacies, a correct geometric argument using addition or subtraction of distances or angles should always prove that quantities are being incorporated with their correct orientation. The fallacy in this proof arises in line 3.

- The implication "Every N horses are of the same color, then N+1 horses are of the same color" works for any N greater than one, but fails to be true when
- Learn more You're viewing YouTube in German.
- If we remove a horse from the group, we have a group of N - 1 horses of the same colour.
- This one's a classic, but people usually don't bother with the explanation, letting morons argue about it in the comments.
- Positive and negative roots[edit] Care must be taken when taking the square root of both sides of an equality.
- As a corollary, one can show that all triangles are equilateral, by showing that AB = BC and AC = BC in the same way.

When treated as multivalued functions, both sides produce the same set of values, being {e^{2πn} | *n* ∈ ℤ}. A journey into the foundations of math. Anmelden 243 9 Dieses Video gefällt dir nicht? Prove That Papa=mama In fact, O always lies **at the circumcircle of** the △ABC (except for isosceles and equilateral triangles where AO and OD coincides .

Because, as we've been taught forever, it's never OK to divide by zero!Why Can't You Divide By Zero?Which might get you wondering: Why exactly is it that we can't divide by Prove 1+1=3 If a = 0 then b should also be equal to 0 because we considered a = b at the beginning.

Calculus[edit] Calculus as the mathematical study of infinitesimal change and limits can lead to mathematical fallacies if the properties of integrals and differentials are ignored. Let's imagine for **a second** that division by zero is fine and dandy.

## Prove 1+1=3

Draw line OR perpendicular to AB, line OQ perpendicular to AC Draw lines OB and OC By AAS, △RAO ≅ △QAO (∠ORA = ∠OQA = 90; ∠RAO = ∠QAO; AO = here Du kannst diese Einstellung unten ändern. 2=1 Proof The error in each of these examples fundamentally lies in the fact that any equation of the form x 2 = a 2 {\displaystyle x^{2}=a^{2}} has two solutions, provided a ≠ How To Prove 2+2=5 Think that sounds ridiculous?

There is a distinction between a simple mistake and a mathematical fallacy in a proof: a mistake in a proof leads to an invalid proof just in the same way, but So the correct fourth roots are i and −i, which are the imaginary numbers defined to square to −1.

Courier Corporation. 2 For 1 Meaning OK, I'll prove it to you. By eliminating y, solve the simultaneous equations?

## Take a minute and see if you can figure it out…OK, got it?It happened when we divided both sides bya -b in the fifth step.

Proof by induction[edit] There exist several fallacious proofs by induction in which one of the components, basis case or inductive step, is incorrect.

Explain the error in the following false proof.? x=y X^2=xy X^2-y^2=xy-y^2 (x+y)(x-y)=y(x-y) ((x+y)(x-y)/(x-y))=(y(x-y)/(x-y)) X+y=y Y+y=y 2y=y (2y/y)=(y/y) Log On Ad: Mathway solves algebra homework problems with step-by-step help! The error is here: ((x+y)(x-y)/(x-y))=(y(x-y)/(x-y)) Because we know that x=y So x-y = 0 And we cannot divide by zero. ⌂HomeMailSearchNewsSportsFinanceCelebrityWeatherAnswersFlickrMobileMore⋁PoliticsMoviesMusicTVGroupsStyleBeautyTechShoppingInstall the new Firefox» Yahoo Answers 👤 Sign in ✉ Mail http://indywebshop.com/find-the/find-the-error-111-222.php subtract b^2 from both sides to get a^2 - b^2 = ab - b^2.
