An interactive presentation of maple 3D graphics in PDF documents.
Oct 01, 2008; ... Abstract The paper presents the authors' experience with including interactive 3D objects into PDF documents, starting with modifying 3D graphics in Maple, followed by its export into the VRML format, then its conversion to U3D with the use of Deep Exploration, and finishing ...
Integration on Computer Algebra Systems.
Oct 01, 2008; ... Abstract In this article, we consider ten indefinite integrals and the ability of three computer algebra systems (CAS) to evaluate them in closed-form, appealing only to the class of real, elementary functions. Although these systems have been widely available for many years and ...

Oct 01, 2008; ... Abstract This paper contains an overview of personal experiences of the author in teaching mathematics with computer technology. Different aspects of teaching mathematics with computer technology are analyzed. The usability of selected computer tools for mathematics classes is ...
A mathematical modeling project using MATLAB[R].
Oct 01, 2008; ... Mathematical software has been playing an important role in teaching and learning. This paper reports the students' performance and reaction on the use of MATLAB[R] for a modeling project at the National Taiwan Normal University. It was the first time a mathematical modeling project had ...
General inverses in 2-D, 3-D, applications inspired by technology.
Oct 01, 2008; ... Abstract We first generalize the concept of inverse images with respect to the line y = x to the inverse images with respect to y = mx + b, and we extend the idea to three dimensions. Next, we find the reflection of a point on curve [C.sub.1] with respect to a moving point P on ...
Understanding and developing proofs with the aid of technology.
Oct 01, 2008; ... Abstract: This paper continues the work entitled On Proof Techniques and Technology [2], which discusses strategies on how technology may be used to explore and understand mathematical ideas, and develop different kinds of proofs. 1. Introduction Proofs play an ...
Visual angle on the unit sphere.
Oct 01, 2008; ... Abstract Let AOB be a triangle in the three dimensional Euclidean space [R.sup.3]. When we look at this triangle from various viewpoints, the angle [angle]AOB changes its appearance, and its 'visual size' is not constant. This visual angle is realized on the unit sphere ...
