The other subjects, such as mathematics, trigonometry material is structured and organized as well as, trigonometry subjects should also be understood from the basic framework. The basic of trigonometry is students must be able to determine the comparative value of trigonometry appropriately. One way to facilitate the students in order to determine easily the value of a special angle is using ?the five finger technique? trigonometry. Through this technique, The writer is expected that students can easily remember and memorize the basic concept of determining the comparative value of trigonometry with special angle.]]>
