Integration

This series of excel sheets look at the area of regions bounded by linear and quadratic graphs.

The first interactive sheet calculates the area under the line y = mx + c between limits A and B. The effect on the area...

Interest: Simple and Compound

The first interactive sheet shows a calculator for Simple Interest where the amount invested, the rate of interest and the term can be altered. The next sheet shows sets of five questions on Simple Interest to be answered with the help of calculators. Answers can be...
