This Program is for the novice user of the TI-89, or anyone who does not want to search for commands built into the TI-89. AMENU, meaning ALGEBRA MENU, brings up 9 choices: 1: Solve (Equation, Inequality, System), 2: Quadratic (Solves, finds vertex and focus, and Graphs), 3: Lines (Two Points, Pt-slope, x-int & y-int, Pt-parallel, Pt-perpendicular, Slope & y-int, Ax + By = C, Pt-vertical), 4: Best Fit (Shows graph and equation for regression types, Linear, Quadratic, Cubic, Quartic, Power, Exp, Ln, Med-Med, Logistic, and Sine), 5: Radical (Simplifies the nTH root of b), 6: Polynomial (Multiply, Factor, Divide, Combine, Simplify), 7: Two Lines (Graphs two lines, shows the intersection, if any, and the intercepts), 8: Functions (Composite and Inverse), 9: Shade (Graphs a system of inequalities in x and y and shows the solution region).
