<![CDATA[The purpose of this research is (1) analyze student?s concept in answering the association test, (2) analyze the concept of understanding relationship to answer the test depends on the student?s school origin.The method used in this research is qualitative with case study approach. In clustering sampling technique the subject was used in this research is 6 students, shared in 3 groups. They are 2 students come from public vocational school, 2 students come from public senior high school and 2 students come from private senior high school and vocational school. Data was collected through test and interview. Data analysis used in this research refers to Milles and Huberman in Moellong?s book; they are data reduction, data display and conclusion drawing. The result showed that the student?s understanding is various enough in answering the set test. Depending on the first subject analysis (S1) who came from private school, he did not understand about the concept of set. The second subject analysis (S2) and the third subject analysis (S3) who came from public school, they had understood. But, they need to be careful and patient to avoid the mistakes. The data which had gained from deeply interview, showed that the subject analysis (S1), (S2) and (S3) were able to indicate the relationship of school origin with the student?s concept of understanding within answering the set test.]]>

<![CDATA[Most of Students in High School are not mastering in Trigonometry subject. It is because the learning trigonometry arithmetic is new material on the curriculum in High school level and even just a little discussed in class IX of junior high school level. Then, in learning trigonometry the students are required to memorize a lot of formulas and should be able to use the formula quickly. 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.]]>

<![CDATA[Trigonometry is the uppermost group of the most difficult materials collection in mathematics. Trigonometry is belonging to the materials that have the greatest number of concept even trigonometry is well known by the quantity of formula or identity and application from trigonometry. They are establish that trigonometry is a very important material. In fact, the majority of students which dislike the trigonometry and they have low mark even the lowest from another topics in mathematics. The main factor is the teacher. The teacher is lack innovative in teaching trigonometry material even the difficulties degree of trigonometry material same with the difficulties degree of the students which receive the material from their teacher. In order that, the writer try to give an idea which can be an alternative in teaching learning trigonometry, especially angles relations which have tens of angles relations. In determine the angles relations each quadrant, it can using the graph functions of sinus and cosines. It means that the graphs method can be an alternative in teaching learning trigonometry, especially angles relations.]]>
