CHAPTER 6 Proof by Contradiction
... statement P ⇒ Q , we might begin with direct proof and thus assume P to be true with the aim of ultimately showing Q is true. But the truth of Q might hinge on the truth of some other statement R which—together with P —would imply Q . We would then need to prove R , and we would use whichever proof ...

... (d) Construct graphs achieving each of the values of d you found in the previous part. For (d, n) = (3, 4), we must take the complete graph K4 . For (d, n) = (4, 16), there are two solutions. One is the graph whose vertices are ordered pairs (x, y), with x and y ∈ {1, 2, 3, 4}, and an edge between ( ...

LINEAR DIFFERENTIAL EQUATIONS WITH CONSTANT
... this is usually quite demanding. It would, therefore, be pedagogically interesting to have a simpler alternative to this method. In this paper we have presented such a method which requires only differentiation and some additions. Several examples have been included to manifest its versatality. It ...
