1. Propositional Equivalences Rosen 5th and 6th Editions section 1.2

2. I assume you know what follows

6. Okay?
If not then please read appropriate section from Rosen

9. //
// are functions f and g logically equivalent?
public class Obfuscate {
public static boolean f(int x,int y){
boolean z;
if (!(x>5 || (x<=5 && y<3)))
z = true;
else
z = false;
return z; }
public static boolean g(int x,int y){return x<=5 && y>=3;}
public static void main(String[] args) {
int n = Integer.parseInt(args[0]);
int m = Integer.parseInt(args[1]);
System.out.println(f(n,m) + " " + g(n,m));

10. What’s the difference between
& and &&
| and ||

13. Can you think of a reason why we might use
| in place of ||
& in place of &&
