The equation for a circle is confirmed to be correct, with a focus on the properties of disjunction in logic. The discussion highlights that disjunction is idempotent, meaning $x \lor x \iff x$. There is a suggestion to utilize $\LaTeX$ for clearer mathematical representation. Additionally, a note is made about an image being cropped on the right, which may affect clarity. Overall, the conversation emphasizes the importance of proper formatting in mathematical discussions.

Your image seems to be cropped on the right.
For something like this, it would be better to use $\LaTeX$. All of the symbols you need are in the "Set Theory/Logic" section of our "Quick $\LaTeX$" element:
[table="width: 200, class: grid"]
[tr]
[td]Command[/td]
[td]Output[/td]
[/tr]
[tr]
[td]\lor[/td]
[td]$$\lor$$[/td]

[td]\And[/td]
[td]$$\And$$[/td]

[td]\iff[/td]
[td]$$\iff$$[/td]

Yes. Disjunction is idempotent: $x\lor x\iff x$.hossam killua said:
