Two more limits

| The graph of the function f(x) = sin(x)/x. Even though f(0) is undefined, the diagram shows that f(x) --> 1 as x --> 0. | |

| Graphs of the functions f(x) = -|x| (in blue), g(x) = x sin(1/x) (in green) and h(x) = |x| (in red). Notice how the graphs of f and h ``squeeze'' together as x --> 0, forcing g(x) --> 0. |
