## 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.**
