# Math Help - Area under curve

1. ## Area under curve

Hello,

Please could someone show me how to find the area between the "Loading trendline 1" line and the x-axis?

Please could you also show me how to find the area under the "Unloading trendline 1" line?

Assume both lines extend to the top of the graph area.
