  • This research was descriptive quantitative intended to describe learning process with the application of APOS based mathematical learning approach and students' learning outcomes after the implementation of APOS based mathematical learning approach on the trigonometry functions graphics subject. The research subjects are the students of X-EXACT 1 class of Senior High School 1 lndralaya 2017/2018 which consist of 26 students. The learning process went right according to the steps of APOS based mathematical learning approach. The data collecting technique used are observation, to saw the implementation of APOS based mathematical learning approach, and test consist of 3 questions to saw the students' learning outcomes. According to the result obtained by the implementation of APOS based mathematical learning approach to saw the learning outcomes of X-EXACT 1 class of Senior High School 1 lndralaya students generally went well, with the average of 12, 54 completion of four steps of APOS based mathematical learning approach. The average of students learning outcomes are 67,18 in average category which is: remembering indicator is 9,69, understanding indicator is 6,65, application indicator is 1, 15, and Analyzing indicator is 2,65.
