"Do we really need integrals?"

|Abstract: The area of a triangle is 1/2*(base)*(height), and we donâ€™t need any fancy tool to verify this formula.(Simply cut the triangle a couple of times and then reassemble those pieces to make a rectangle.) Then how about the 3-dimensional version of a triangle, namely a tetrahedron? The volume of a tetrahedron is 1/3*(bottom)*(height), and one way to verify this formula is to use the integral. My question is, is there an elementary way to verify this formula, especially without using integrals? In this talk, we will investigate the answer to this question, and see if we can get closer to many young studentsâ€™ dream: math without calculus.|
