Integrals

You can use multiple integrals to define a region by clicking the 'Add Integral' button multiple times. Clicking the 'Remove Integral' button will remove one integral at a time from the list.

Edit Lines

You can use the 'Edit Lines' button to add lines and curves to the diagram to help you determine the appropriate limits.

Problem

Write down the 2-D integral which defines the area between the curves $y=2x^2$ and $y=1.3-(x-1)^2$ between $x=0$ and the point at $x>0$ where the curves cross.

Then write down the 2-D integral integrating over the other variable first. (Note that this has to be done by breaking the integral into different parts.)
