TRIGONOMETRIC FUNCTIONS at your FINGERTIPS

This video will teach you how to evaluate the values of some trigonometric functions with 30-45-60 degrees angles using your fingers.

This technique allows you to easily remember the values of those functions by assigning angles on each finger of your hand.

Enjoy watching and learn.
