I don't know what ≡ means.I don't know what ≡ means in krassi's topic. igloo myrtilles fourmis #2 20060220 03:19:38
Re: I don't know what ≡ means.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? Last edited by irspow (20060220 04:10:17) #3 20060220 04:28:51
Re: I don't know what ≡ means.x ≡ y out loud is "x is equivalent to y". What does equivalent mean? Depends on where you see it. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #4 20060220 05:11:33
Re: I don't know what ≡ means.Yes, I learnt it as being 'identical to' too. Why did the vector cross the road? It wanted to be normal.
