Finding the Maximum Value of ad - bc
2016-01-18 12:04
This applet explores finding the maximum value of ad - bc under the constraints a² + b² = 1 and (c-4)² + (d-2)² = 5. Variables are transformed into points and vectors, utilizing circle equations and the geometric meaning of the vector cross product to visually demonstrate and solve the optimization problem. Ideal for teaching coordinate geometry.
