Mathematical Database MATHEMATICAL INDUCTION 1. Introduction Mathematics distinguishes itself from the other sciences in that it is built upon a set of axioms and definitions‚ on which all subsequent theorems rely. All theorems can be derived‚ or proved‚ using the axioms and definitions‚ or using previously established theorems. By contrast‚ the theories in most other sciences‚ such as the Newtonian laws of motion in physics‚ are often built upon experimental evidence and can never be

Propositions The fundamental objects we work with in arithmetic are numbers. In a similar way‚ the fundamental objects in logic are propositions. Definition: A proposition is a statement that is either true or false. Whichever of these (true or false) is the case is called the truth value of the proposition. Here are some examples of English sentences that are propositions: ‘Canberra is the capital of Australia.’ ‘There are 8 days in a week.’ ‘Isaac Newton was born in 1642.’ ‘5 is greater

in the desert 2x + 6 paces from Castle Rock. Vanessa has the other half of the map. Her half indicates that to find the treasure‚ one must get to Castle Rock‚ walk x paces to the north‚ and then walk 2x + 4 paces to the east. If they share their information‚ then they can find x and save a lot of digging. What is x? So‚ if you walk x paces north‚ then 2x+4 paces east‚ you have moved roughly east northeast to a distance of 2x+6 paces. This is a right angle‚ with 2x+6 on the hypotenuse or line

CHAPTER 2 LOGIC Introduction: Logic is the discipline that deals with the methods of reasoning. On an elementary level‚ logic provides rules and techniques for determining whether a given argument is valid. Logical reasoning is used in Computer Science to verify (menentusahkan) the correctness (kesahihan) of programs and to prove (membuktikan) theorems. 2.1 Proposition and Logical Operations • Statement or proposition → declarative sentence that
