Area Between the Graphs of Sine and Cosine in Single-Variable Calculus
This concept covers computing the area of the region enclosed between two curves using definite integration, formalized as the integral over an interval of the difference between the upper and lower functions (top minus bottom). It relies on identifying intersection points of the two curves as the bounds of integration and on the definition of area as the limit of a sum of infinitesimal rectangle heights times an infinitesimal width dx. This belongs to single-variable calculus, within the theory of applications of the definite integral, extending the basic area-under-a-curve concept to area-between-curves.
