- Take note of what you did in Lesson 1. (You're not asked to redo Lesson 1; just take note of the points made there.)
In the following problems, don't be afraid to address the possibility that the original statement might have more than one meaning, and hence there might be more than one negation; but don't stretch the meanings -- use natural, everyday meanings of the given statements.- Sect. 1:
- Exercise 1.4*(a)-(d)**, and add
* Be sure all your negations are clearly and unambigously the negation of the original statement. Use your judgment as to whether explanations are required. In some cases, you may validly conclude that your answer is “obvious” from the discussions of negations given in the textbook. (See homework policies.)
- The functions f and g are continuous.**
- Bob and Betty are related.**
- Chris and Robin are married.**
** In Exercise 1.4, some of the “statements” contain one or more “variables”. (Even Bob, Betty, etc., in 1.4 (i) and (j) could be considered “variables”.) Assume that the value of the variable is given, so that these are really statements. In Section 1.2, we will learn another way of dealing with “unintroduced” variables.
