Based on the study of the researcher's literature, one of the problems faced by students in learning mathematics is the difficulty with the flat sided space material in terms of instilling concepts. To overcome these problems, an educator can design Student Worksheets (SW) as an effort to help students overcome difficulties in learning. Thus, this study aims to produce an Electronic Student…
Educators must be able to create learning tools that are able to bring out the potential and abilities of students, improve the abilities they already have so that they are able to create and interpret an understanding in their own way. This study aims to produce a learning tool consisting of a syllabus, lesson plans and worksheets with the application of the discovery learning model to facilit…

This final project presents a proof of the butterfly and double butterfly theorems on parabola and ellipse using Haruki’s lemma. In addition, this final project also shows the use of modifications of Haruki’s lemma on a parabola and Haruki’s lemma on ellipse for each proof step. Keywords: Butterfly theorem, double butterfly theorem, Haruki’s lemma on parabola, Haruki’s lemma on e…
ABSTRACT This final project discusses a fifth-order convergence method to solve nonlinear equations by modifying Newton’s method using variational iteration techniques. It is analytically shown that the resulting method has fifth-order convergence. The computational results support the results of the analytical study. Numerical computation shows that the resulting method is comparable to…
ABSTRACT This final project discusses the development of the concept of a mixtilinear incircles in a cyclic quadrilateral. The development carried out is to show the various relationships formed between the mixtilinear incircles radii that can be constructed on the cyclic quadrilateral. In any triangle ABC, three different mixtilinear incircles can be constructed. In this final project, po…
This research is motivated by the low mathematical problem solving ability of students. One of the efforts that can be made by teachers to improve mathematical problem solving skills is to design the learning process. The learning process can take place well if the teacher is able to develop learning tools. Based on observations and interviews conducted with three mathematics teachers, nam…
This final project discusses Gradient Descent method with the explicit stepsize formula for solving systems of nonlinear equations. Gradient Descent method with the explicit stepsize formula has linear convergence and if the Jacobian matrix has a special structure then it is equivalent to Newton’s method which quadratic convergence. At the end of the discussion, some numerical examples a…
ABSTRACT This nal project discusses the multiplicative functions commutable with sums of squares. In this nal project, suppose that k be an integer greater than or equal to 3. It is shown that if a multiplicative functions f satises f(x2 1 + x2 2 + · · · + x2 k) = f(x1)2 + f(x2)2 + · · · + f(xk)2 for all positive integers xi, then f is the identity function. This nal project i…
The final project discusses the development of converse Leon Anne’s Theorem in crossed quadrilateral. This theorem initially applies to a convex quadrilateral with the balance property obtained if the area of two opposite triangles is half the area of the quadrilateral. In the case of the a crossed quadrilaterals, balance property is obtained from the difference of the area of two certain…
