PPT-Methods of Proof

This Lecture Now we have learnt the basics in logic We are going to apply the logical rules in proving mathematical theorems Direct proof Contrapositive Proof by contradiction Proof by cases. You can trust the revolutionary smell proof Gonzo Bag to safely store and totally eliminate odor emissions from whatever you have stored inside the bag. The unique design, combining an activated charcoal filter with a double walled bag and reusable enclosure will allow you to store many odoriferous substances, such as food, diapers, dog poop bags, herbs, and any smelly organic materials that you don't want to smell for weeks or months. You can use it to store food and keep it safe from bears and other animals while camping. The basic idea is to assume that the statement we want to prove is false and then show that this assumption leads to nonsense We are then led to conclude that we were wrong to assume the statement was false so the statement must be true As an examp Susan .
