Is it possible to integrate between two graphs on an fx-9860g? I can't seem to figure it out...

I was just checking out my calc because I thought there was an option in the GRAPH mode, but I can't find it...
What you could do though is, in RUN mode, input the integrals in Function Memory, then indicate the first integral (with it's limits) and substract the second integral (with it limits)... And remember to be very careful with this, you need to know what you're doing with the integrals and the area of integration or you'll get the wrong answer.
If you want the area between the two curves bounded by the intersection points, you can solve for them in GRAPH mode, input the functions, draw them, hit G-Solv, ISCT.
Hope it helps.
