What he means is in general ##5a+b\in\mathbb Z\implies a,b\in\mathbb Z ## is false.
I get it now. A little imagination did the trickbaldbrain said:To elaborate more, B ≥ b^{2}/4 + b is a family of parabolas for all values of b and the 'greater than part' represents the locus of the points outside the interval (α,β) if they're the roots of B
how do you order arbitrary complex numbers? The expression ##(x,y) ## as an interval makes sense in this context if they are comparable.baldbrain said:I get it now. A little imagination did the trick
My computer isn't recognising these as symbols, so they're just visible as plain text. Do you mean to say that 5a + b is an integer does not imply a,b are intergers?nuuskur said:What he means is in general ##5a+b\in\mathbb Z\implies a,b\in\mathbb Z ## is false.
