Be able to relate the area between two curves (functions) on a Cartesian graph to the algebraic representation as a definite integral of a difference of those two functions. Be able to compute the definite integral of the area between curves given the two functions represented by the curves and limits. Be able to interpret what the area between curves represent with given business functions (e.g. cost and revenue) and compute the area between curves representing a desired business value (e.g. total net profit).
