This Geogebra file calculates the area under a curve. Use this file to solve questions in Exercise 2C of Cambridge HSC Mathematics General 1. To use this file:[br][br]- set n to 4 (number of partitions);[br]- vary points A and B for the Base line of the Simpson's Rule;[br]- vary the distance of the first line ([i]d[sub]f[/sub][/i]) by varying the constant (value after the function);[br]- vary the irregular boundary by choosing a function for the curve (sin, cos and tan).[br][br]The distance of the last line is set by the function.
