It's like: It's okay to do the thing in $12x=12$, but for doing it on $(x+y)(x-y)=y(x-y)$ we need first to simplify $(x+y)(x-y)$ to $x^2-y^2$.
I have a "proof" that has an error in it and my goal is to figure out what this error is. The proof: If $x = y$, then $$ \begin{eqnarray} x^2 &=& xy \nonumber \\ x^2 - y^2 &=& xy ...
25 Ιαν 2024 · Cunningham's Law states "the best way to get the right answer on the internet is not to ask a question; it's to post the wrong answer." The concept is named after Ward Cunningham, the inventor of wiki software.
29 Ιουλ 2010 · The equality $nx = x^2$ is not comparable to an equality like $\sin x^2 = 1 - \cos x^2$ : the equation $nx = x^2$ holds for only two values of $x$, where as the trigonometric equation holds for any real/complex value of $x$.
1=2: A Proof using Beginning Algebra. The Fallacious Proof: Step 1: Let a = b . Step 2: Then , Step 3: , Step 4: , Step 5: , Step 6: and . Step 7: This can be written as , Step 8: and cancelling the from both sides gives 1=2. See if you can figure out in which step the fallacy lies.
12 Ιουλ 2022 · Some people think that 1=2, and the math actually makes sense. But can you prove them wrong and find the flaw in their logic?
1=2: A Proof using Complex Numbers. The Fallacious Proof: Step 1: -1/1 = 1/-1. Step 2: Taking the square root of both sides: sqrt (-1/1) = sqrt (1/-1) (where "sqrt" denotes the square-root symbol which cannot be displayed on text-only browsers.)
