KEMAMPUAN MULTI REPRESENTASI MATEMATIS SISWA DALAM KONSEP PERBANDINGAN TRIGONOMETRI SUDUT ISTIMEWA DI SMA

Abstract This research was to describe the ability of students to multi mathematical representations in the concept of a special angle trigonometric comparison. The method used is descriptive. The subjects were all students of class XG SMAN 5 Pontianak. Data collection techniques using measurement techniques employing written tests and interviews. The result showed that 8 students in the upper group, there was one student with the ability of multi-representation that was classified as good with a percentage value of 73.75% of the score obtained 59, one student was sufficient with a percentage of the score of 56.25% of the score obtained 45. Then the remaining six students were less one student with a percentage value of 38.75% of the score obtained 31, one student with a percentage value of 35.00% of the score obtained was 28, two students with a percentage value of 32.50% of the score obtained was 26, one student with a percentage value of 30.00 % score obtained 24, and one student with a percentage value of 27.50% score obtained 22. Keywords: Multi Mathematical Representation Ability, Special Angle, The Concept of Trigonometric Comparison
