About This Lesson
The 39th in Mr Barton's Autograph Video tutorial series. In this video we take a look at the third of Autograph's wonderful Extras pages - Trigonometry. Here we see where the graphs each of the trigonometric ratios comes from using the unit circle, and observe the effect on the graphs where we manipulate some constants. Below the video you will find an option to download it and play it on a larger screen, or by clicking on the web-link you can see all the videos in this series.
A nice tutorial demonstrating how to use Autograph to explore Trigonometry. Video gives step-by-step instructions on how to do this, so that teachers can become familiar with the Autograph software.
