Motivation for Limits: f(x) = sin(x)/x
Consider the function f(x) = sin(x)/x.
We know that f(0) is undefined because of division by zero.
What does the rest of the graph look like?
Drag the point "x" along the x-axis to trace out the graph of f(x).
What does it "look like" f(0) should be?
Click the check box to show the graph of f(x).
Hold down control and use your mouse wheel to zoom in and out.
