Mathematical word problems can be utilized to improve students' mathematic problem-solving skills. However, error still occurs in mathematical problem-solving. This research aimed trace and reveal errors using the Newman Error Analysis stages. is descriptive qualitative research. The subjects were moderate-ability students of State Madrasah Tsanawiyah (MTs) Jambi. problem worksheets interview t...

The dualistic structure of statistical manifolds in information geometry yields eight types (possibly mixed type) geodesic triangles passing through three given points, the triangle vertices. interior angles can sum up to $$\pi $$ like Euclidean/Mahalanobis flat geometry, or exhibit otherwise angle excesses defects. In this work, we initiate study dually spaces, termed Bregman manifolds, where ...

In this paper, we propose a general method to obtain Linearly Independent NonOrthogonal yet Energy (square of the norm) Preserving (LINOEP) vectors using iterative filtering operation and we refer it as Filter Mode Decomposition (FDM). We show that the general energy preserving theorem (EPT), which is valid for both linearly independent (orthogonal and nonorthogonal) and linearly dependent vect...

Learning objects-driven approaches for the development of instructional content have been widely used to structure entire courses and repositories for distinct learning contexts. Nonetheless, their use is still done in a static, non-adaptive manner, since students are presented to prebuilt compilations of learning object having few or none relationship with its learning current conditions, hist...

We study Lévy processes associated with the power-variance family of probability laws. Their path and structural properties as well as the exact asymptotics of the probabilities of large deviations are established. We use the techniques of DoleanMeyer exponentials to introduce an additional class of Lévy processes. The ordinary exponentials of its members constitute the geometric Lévy processes...

This study uses a qualitative descriptive method to categorize the level of mathematical problem solving based on resilience, namely high, medium, and low. The data collection technique used problem-solving ability test Pythagorean theorem material resilience questionnaire. sample this research is VIII grade students SMP Negeri 39 Pekanbaru. study's category students' in high medium categories....

A prime Pythagorean triangle has three integer sides of which the hypotenuse and one leg are primes. In this article we investigate their properties and distribution. We are also interested in finding chains of such triangles, where the hypotenuse of one triangle is the leg of the next in the sequence. We exhibit a chain of seven prime Pythagorean triangles and we include a brief discussion of ...

The main objective of this research was to develop a digital comic based on valid and effective parable story that can improve understanding the concept triangle types with help Pythagorean theorem. method used development using Borg Gall model. subjects study were students class VIII A MTs NU 01 Pecalungan Batang, totaling 30 students. Collecting data done through expert validation questionnai...
