“…Many studies have been carried out in increasing students' abilities especially in integral and trigonometric material (Anggraini & Masykur, 2018;Arifudin, Wilujeng, & Utomo, 2016;Arvianto, 2017;Hartono & Noto, 2017;Misrianti, Sugiatno, & Hamdani, 2014;Nurhikmah, Menurut, & Tentu, 2016;Putra & Anggraini, 2016;Rumasoreng & Sugiman, 2017;Susilo & Khabibah, 2013) because trigonometric material is considered important to be mastered as well as research that analyzes students' errors by reviewing it using Solo Taxonomy (Azizah, 2015;Ghati, 2018;Lipianto et al, 2013;Manibuy, Mardiyana, & Saputro, 2014;Pesona, 2018;Rosyida Ekawati dkk, 2013;Tarigan, 2014;Widyawati, Afifah, & Resbiantoro, 2018) However, there has been nostudy that reviews students' error in calculating the definite integral of trigonometric functions using Solo Taxonomy. So, this study aims to review students' error in calculating the definite integral of trigonometric functions using Solo Taxonomy.…”
