Two young mathematicians discuss cutting up areas.

Check out this dialogue between two calculus students (based on a true story):

Devyn: I’m tired of Riemann sums.
Riley: Can’t we use high school geometry to compute integrals?

Which curves are good for using high school geometry to compute the area?

Answer will vary.
