Monday, August 8: Samples of Proofs
... Let a b = a + b + 4. Then a k = a + k + 4 and if a + k + 4 = a, then k = -4. Consider k = 4. a 4 = a + 4 + 4 = a for all real values of a, and 4 a = 4 + a + 4 = a for all real numbers a. Hence if a b = a + b + 4 , then a 4 = 4 a = a for all a Reals. Proof by Induction: (Set up ...

Verification and Specification of Concurrent Programs
... a terminating execution is represented by an infinite behavior in which the final state is repeated.) The meaning [[P ]] of a predicate P is a Boolean-valued function on program states. For example, [[x + 1 > y]](s) equals true iff one plus the value of x in state s is greater than the value of y in st ...

Introduction to Functions
... Exercise #3: The distributive property can be used twice in order to multiply two digit numbers. For example find the product 12 28 by evaluating 10 2 20 8 . Show each step in your calculation. Do not use a calculator unless it is to check. ...

The Arithmetic-Geometric Mean
... Suppose you want to compute the average of a set of numbers. There are a number of ways of doing this; for example, if you arrange the numbers in order in a list, the value in the middle of the list is called the median average. You may have a set of numbers in which the same number occurs more than ...
