Description

There are some key angles that have exact values in trigonometry. The ones we need to know are 0, 30, 45, 60 and 90.

In this video we will discover one method of remember what these values are - by counting fingers on our hand!

In the first part we discovered a different method (constructing a table) which you may prefer. Choose whichever method works best for you.
