Segitiga asal dalam skripsi ini adalah sebarang AABC, dari segitiga tersebut dapat ditentukan excenter-excenter, kemudian dengan menghubungkan excenter-excenter tersebut dapat terbentuk segitiga excentral yang dinotasikan dengan , jika ditarik ketiga garis tinggi maka akan tepat di A, B dan C, sehingga sebarang AABC disebut juga segitiga orthoptic. Selanjutnya dari titik-titik sudut Aa deng…
ABSTRACT By using Problem Based Learning (PBL), this classroom action research seeks to improve the learning process and increase students' mathematical problem solving abilities (KPMM). In the even semester of the 2022/2023 academic year, this research was attended by 41 students with various skill levels from class VIII3 of SMP Negeri 17 Pekanbaru. This research was divided into two cycles, …
Abstract: This research is motivated by the objectives of mathematics learning which require students to have mathematical problem solving abilities, but the reality in the field shows that students abilities in solving mathematical problems are still not optimal and are relatively low. This research aims to improve the learning process and increase students' mathematical problem solving (KPM…
This final project discusses a two-step iterative method to solve a nonlinear equation. The method is obtained by substituting the quadratic formula into Taylor expansion, then the second derivative that appears in the formula is estimated using a cubic polynomial. Analytically it is showed, using the Taylor expansion, geometric series and binomial series that the iterative method has the …
