WebWhat we can say though, is that if it is true, then: x 2 ≥ y 2 x 2 − y 2 ≥ 0 ( x − y) ( x + y) ≥ 0 At this point there are two possibilities: either both ( x − y) and ( x + y) are nonnegative, or one is nonpositive and the other is negative. In the former case, x − y ≥ 0 x ≥ y. WebThe symbol for ‘if and only if’ is ‘ ⇐⇒ ’. When p ⇐⇒ q is true, we say that p and q are equivalent. 1.2 Quantiﬁers Consider the sentence x is even.
