Applet explorations

1) Extend your methods from the previous task to find the pink shaded area. You will need to complete your calculations by hand now! Type your answer to 2 decimal places in the answer box once you have finished – make sure you use exact values in your calculations to avoid rounding errors. 2) Change the function and move the sliders to try another problem. Does the general method you developed in the previous task still work? Summarise any key points at the bottom of the page.
