Use Web-based Simulation to Learn Trigonometric Curves
نویسندگان
چکیده
The purpose of this study is to investigate the impact of using Trigonometric Graphs, a teacher created web-based simulation, and asynchronous online discussion on students’ understanding of and performance in sketching transformation of trigonometric curves. The participants of the study were 29 Grade 9 students from a Singapore school. The students worked in groups of three or four in experimenting with the web-based simulation to learn to sketch stretches and translations on trigonometric curves. The students also learned to decipher the concept behind each transformation through an online discussion forum. A diagnostic quiz was used to assess the students’ abilities of sketching transformations, and an oral examination was administered to evaluate their understanding of the concepts behind the transformations. The findings show that self-experimentation with the web-based simulation and online discussion forum helped improve the students’ abilities of sketching singular/combined transformations and explaining the concept behind each transformation.

A new kind of quasi-quartic trigonometric polynomial base functions with a shape parameter λ over the space Ω=span {1, sint, cost, sint2t, cos2t} is presented, and the corresponding quasi-quartic trigonometric Bézier curves and surfaces are defined by the introduced base functions. The quasi-quartic trigonometric Bézier curves inherit most of properties similar to those of quartic Bézier curves...
متن کاملDesign and Simulation of a Modified 32-bit ROM-based Direct Digital Frequency Synthesizer on FPGA
This paper presents a modified 32-bit ROM-based Direct Digital Frequency Synthesizer (DDFS). Maximum output frequency of the DDFS is limited by the structure of the accumulator used in the DDFS architecture. The hierarchical pipeline accumulator (HPA) presented in this paper has less propagation delay time rather than the conventional structures. Therefore, it results in both higher maximum ope...
متن کاملA Method for Local Interpolation with Tension Trigonometric Spline Curves and Surfaces
In this work a family of tension trigonometric curves analogous to those of cubic Bézier curves is presented. Some properties of the proposed curves are discussed. We propose an efficient interpolating method based on the tension trigonometric splines with various properties, such as partition of unity, geometric invariance and convex hull property, etc. This new interpolating method is applied...
متن کاملConical representation of Rational Quartic Trigonometric Bèzier curve with two shape parameters
I. Introduction Rational spline is a commonly used spline function. In many cases the rational spline curves better approximating functions than the usual spline functions. It has been observed that many simple shapes including conic section and quadric surfaces can not be represented exactly by piecewise polynomials, whereas rational polynomials can exactly represent all conic sections and qua...
