Abstract
Abstract. This article would like to explain the source of learning obstacle on Trigonometric concept, especially learning obstacle to solve the trigonometric function. The subject of this research were thirty six students of Senior high School. Method of research was qualitative. This research found that the learning obstacle was caused of miss preliminary knowledge of algebra concept such as degree measurement, the concept of sine, cosine, and tangent which are the specific concept in Trigonometric. To overcome the learning obstacle is needed special learning trajectory of Trigonometric concept.
