## Exploring MathematicsExploring Mathematics: Solving Problems with the TI-84 Plus Graphing Calculator is a useful manual that provides students in precalculus, college algebra, and trigonometry courses with instruction on how to use a graphing calculator to solve a number of problems in their textbook. Students are urged to first make a conjecture about the solution based on their previous experience and knowledge from other math courses, and then test that conjecture with the aid of a graphing calculator. All references in the manual refer to the TI-84 Plus graphing calculator; however many of the keystrokes described also apply to the TI-83 Plus. Topics covered include: Viewing Rectangle, Graphing Equations, Intercepts & Symmetry, Solving Equations, Square Screens, Graphing Inequalities, Systems of Equations, Polar Equations, Parametric Equations, Least Square Line. |
