Abstract | This paper reports the results of student use of a TI-92 graphing calculator to solve algebra and analytic geometry problems in 9th grade Austrian classes. Students who had been trained in using the TI-92 were asked to compute x, given that a right-angled triangle had sides x, x+3, and x+6 in at least three ways, and to document their solution methods. An analysis of the frequency of a variety of methods including solving, graphing, using a table, and solving by hand is included. A similar analysis is carried out for a problem in analytic geometry.
