Approximating area: the Trapezium Rule by Gemma Cliffe

This example demonstrates how to approximate the area under a curve using the trapezium rule. Key mathematical concepts include integration and trapezoidal approximation. Construction involves commands like Point, Textfield, TrapezoidalSum, and Integral, with objects such as A, B, f, inputBox1, etc. Suitable for high school students or college freshmen learning calculus basics or geometric transformations.
