“…So based on the results of the research obtained through the answers and interviews above that S1 before solving the problem, S1 finds the size of the angle using the concept of completing perfect squares, then adjusts the size of the angle obtained with the rules for the value of the angle using the direction of quadrants 1-4. This is in accordance with previous findings; students can analyze and examine errors found in the answer sheets for trigonometry questions related to determining angles (Hidayati, 2020;Indrawatiningsih et al, 2019). So based on the research results obtained through the answers and interviews above that S2 before solving the problem, S2 looks for the size of the angle using the quadratic equation, but S2 has not yet completed finding the most likely angle from quadrants 1 -4, where S2 is just looking for the size of the angle from quadrant 1 -2.…”

“…Dalam konteks subjek matematik, Indrawatiningsih et al (2019) menyatakan masih ramai murid sekolah tidak meyukai topik trigonometri kerana mempunyai miskonsepsi yang salah terhadap topik ini walaupun ia adalah topik asas. Sesetengah murid sering mengalami kesukaran semasa mempelajari trigonometri kerana mereka tidak memahami asasnya.…”

“…Walaupun terdapat banyak kajian tentang miskonsepsi dan motivasi, sebilangan kecil penyelidik telah mengambil kira Kemahiran Berfikir Aras Tinggi. Menurut definisi KBAT, dapat disimpulkan bahawa pemikiran KBAT adalah pemikiran introspektif dan logik yang digunakan dalam penyelesaian masalah, pengambilan keputusan, dan penjelasan konsep (Indrawatiningsih et al, 2019). Kemahiran Berfikir Aras Tinggi (KBAT) ialah keupayaan untuk menggunakan kepakaran, kebolehan, dan prinsip dengan membuat penaakulan dan refleksi untuk menyelesaikan isu, membuat pilihan, berinovasi dan boleh mencipta apa sesuatu (Kementerian Pendidikan Malaysia, 2013).…”

“…Facione (2013) menjelaskan bahwa evaluasi: untuk mengidentifikasi dan mempersetasikan bagian penting untuk mengambil kesimpulan yang logis; untuk membuat asumsi dan hipotesis; untuk mempertimbangkan keterangan yang relevan dan mengembangkan hal penting dari suatu data, pernyataan, hukum, bukti, penilaian, kepercayaan, pendapat, bentuka rancangan, gambaran, dan pertanyaan. Lebih lanjut menurut Indrawatiningsih et al, (2019) inferensi adalah kemampuan yang dimiliki oleh siswa untuk menarik sebuah kesimpulan berdasarkan pernyataan. Pada aspek ini siswa tergolong rendah dengan persentase 41,94%.…”
