I am learning calculus and am at the point where we switch from differentiation to integration. What is the point of finding the area of a certain graph under the curve?
So far I do understand and am learning how to find the area under the curve using Riemann sums but my teacher is not clear on what the point of it is.

The area under a curve is its integral. Many many physical, chemical, financial, and other variables are related by such integration. For instance if you have a speed as a function of time ($v(t)$), you can find the position $x(t)$ (up to a constant) by integrating the speed.
