used for identities (trigonometry) to indicate that something is always true - in trigonometry true for any angle for example.
Yes, I learnt it as being 'identical to' too.
x ≡ y out loud is "x is equivalent to y". What does equivalent mean? Depends on where you see it.
I believe that it means that the term on one side is the definition of the term on the other side. They are more than just terms that are equivelent but exactly the same. Does that make sense?
I don't know what ≡ means in krassi's topic.
