AI Thread Summary
The binary operator $\oplus$ is defined as $a \oplus b = 4ab$, with examples showing its application, such as $9 \oplus 3 = 108$ and $2 \oplus 2 = 16$. The significance of $\oplus$ varies depending on the context, as binary operations can be relevant in many mathematical problems and relations. Participants express confusion over its simplicity and mention a lack of exposure to such concepts in their education. The discussion highlights that binary operations are foundational in understanding relations in mathematics. Overall, the operator's significance lies in its versatility across different mathematical contexts.

define the binary operater $\oplus$ by
a$\oplus$b=4ab
find

a. $9\oplus 3$=4(9)(3)=108
b. $2\oplus 2$=4(2)(2)=16
c. $3\oplus 9$=4(3)(9)=108
d. $g\oplus h$=4(g)(h)=4gh

ok that was too simple must be doing something wrong

what is the significance lf $\oplus$

Nope. It's that simple. As to the significance of [math]\oplus[/math] that depends on the context of the problem. Binary operations can be defined for many specific types of problems.

ok i never saw this stuff in any class i took
not even sure what class its found in

In one form or another you can find them anywhere relations are mentioned. A binary operation is an example of a relation.

Thread 'Video on imaginary numbers and some queries'

Hi, I was watching the following video. I found some points confusing. Could you please help me to understand the gaps? Thanks, in advance! Question 1: Around 4:22, the video says the following. So for those mathematicians, negative numbers didn't exist. You could subtract, that is find the difference between two positive quantities, but you couldn't have a negative answer or negative coefficients. Mathematicians were so averse to negative numbers that there was no single quadratic...

Thread 'Unit Circle Double Angle Derivations'

Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...

Thread 'Fermat's Last Theorem'

Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
