We will do this a little later—after we have introduced the 8 valid forms of inference that you will need in order to do proofs. Each line of the proof will be justified by citing one of these rules, with the last line …

As we will see in this chapter and the next, a proof must follow certain rules of inference, and there are certain strategies and methods of proof that are best to use for proving certain types of assertions.

Proofs are examples of exhaustive deductive reasoning that establish logical certainty, to be distinguished from empirical arguments or non-exhaustive inductive reasoning that establish …

Nov 8, 2023 · In this post, we’ll explore two main methods for testing the validity of arguments: truth tables for simple arguments and formal proofs for more complex ones. By the end, you’ll be …

Writing proofs is difficult; there are no procedures which you can follow which will guarantee success. The patterns which proofs follow are complicated, and there are a lot of them. You can't expect to do …

To convince your marker that you know what you’re talking about, you can’t just make a statement and expect them to accept it; you will need to provide robust evidence to justify your point, show how you …
