By permitting students to experiment with “new” forms of learning and “seeing” mathematics, graphing calculators affect the learning process and, as a consequence, can put pressure on teachers and curriculum developers concerning the teaching process. In this way, when adequate conditions are given, this new technology can reinforce the change process that is taking place in the teaching and le...

One of the strengths of a graphics calculator is the potential it offers for students to explore mathematical ideas from a few different perspectives. A good example of this involves the normal probability distribution, frequently encountered in senior secondary courses involving statistics. This note describes a few ways in which the Casio cfx-9850G series of calculators can be used to evaluat...

BACKGROUND AND PURPOSE Knowing characteristic adverse events (AEs) and their incidence among patients participating in acute stroke trials may assist interpretation of future studies. We aimed to develop an online tool to inform stroke trial safety. METHODS We identified relevant AEs from patients within the Virtual International Stroke Trials Archive (VISTA), using receiver operating charact...

In the past, rock slope stability analysis were performed either graphically or using a hand-held calculator, but nowadays there are variety of slope stability analysis which can be used according to the field condition and potential failure mode. In 2-D analysis, effect of convex and concave walls are neglected, however concave slopes are believed to be more stable than straight walls due to t...
