... Solution: We suppose that the answer is some number. We don’t know what the answer is, so we’ll call it a  bi , since that can be any number you could think of. In other words, we need to find a and b such that: 4  3i  a  bi Now algebra happens. Square both sides and get 4  3i  a 2  b2  2abi ...

... Euclid’s Proposition 5 says that the base angles of an isosceles triangle are equal. Euclid’s proof was a bit harder than the one suggested in question 1(i), because he had not by that point (i.e. in propositions 1 to 4) shown that two triangles with corresponding sides of the same length are congru ...

... graph induces a metric space on its vertex set, where the distance between two vertices u and v is defined as the length of a shortest path linking u and v. Such metric spaces are called graph metrics and are the subject of this paper. The best known lower bound on the number of lines in a graph met ...

... Connectivity. In a simple graph, a path from u ∈ V to v ∈ V can be described by a sequence of vertices, u = u0 , u1 , u2 , . . . , uk = v, where we have an edge from ui to ui+1 for each 0 ≤ i ≤ k − 1. Vertices can repeat allowing the path to cross itself or fold onto itself. Definition A. A simple g ...
