This week in calculus we learned how to find the area between two curves. Like you said, this is fairly intuitive, so it made sense even before the lecture when we tried the exploration. You just subtract the integral of the bottom function (the area under the curve closer to the x axis) from the integral of the upper function (the area under the curve farther from the x axis). I think it actually doesn't matter which function you subtract, because the area between the curves would always be positive so if you end up putting the wrong one first and you get a negative number, just flip it to positive and you are good to go!
