WebIf x is equal to zero, then sin (x) is equal to zero. This statement is certainly true, and its contrapositive is If sin ( x) is not zero, then x is not zero. Again, the contrapositive is certainly true. If we take x to be any value so that is not zero, then x cannot be zero. If the Grass is Not Wet Suppose we are in an open field of grass. WebThe metric topology on a metric space (X, d) is the topology generated by the basis {B(p, ) : p ∈ X, > 0}. Definition 1.36. A space X is said to be zero − dimensional if and only if it has a basis consisting of sets which are both closed and open. 7 Lemma 1.37. If X is a zero-dimensional space, and Y ⊆ X, then Y is zero-dimensional. Proof.
