Limits help please

[joojoa94]

Hi I have to present this math problem in front of my entire math 101 course and I have no idea on how i should present it. the question is this:

Use a graphing utility to graph the function and approximate the limit. Write an approximation that is accurate to three decimal places.

Lim of (1-cos 2x) / (x) as x approaches 0

How should i go about using my graphing calculator to demonstrate?

You can graph it and/or use the table function...you can actually solve this one for the exact value too if you know the appropriate techniques.
