Abstract:
This graphing calculator includes the standard arithmetic operations as well as the logarithmic, exponential, trigonometric, and hyperbolic trigonometric functions. Expressions are evaluated according to standard mathematical priorities, and parentheses are used for grouping. Up to eight 16 character lines can be displayed, and multiple instructions can be entered on the same line. Last entry replay feature allows checking and editing. As many as 27 numerical values can be stored for later recall. Many options can be accessed through a menu driven interface. As many as four functions defined in rectangular coordinates (or three parametric functions) can be stored, graphed, and analyzed, and the size and scale of the viewing window can be adjusted. Users can trace along a displayed graph while viewing the coordinates of each point. Drawing and shading features allow users to add emphasis to graphs and perform additional analyses. As many as three matrices with maximum dimension six by six can be stored, and standard matrix operations, including elementary row operations, can be performed. Up to 150 statistical data points can be entered and one and two variable analyses performed, including linear, logarithmic, exponential, and power models of regression. This data can be plotted in histograms, scatter plots, and regression equation graphs. Up to three statistical plot definitions can be saved for future use, and up to 37 programs that include extensive control and input and output functions can be entered and stored for future use. A user's guide is also included. (Author/DDD)
