Many quantities in Business and the Sciences result from an accumulation or integration process. For instance, total cost of running a coffee shop for a given month, the total revenue accrued by Local Revenue Authorities over a two[1]year period, the total distance travelled by Inter-City Transport operators, etc. Therefore, accumulation or integration is an everyday experience. In many instances, one can only find information about the rate of change of the desired quantities.

Integral calculus is the branch of Mathematics that deals with techniques that lead to complete knowledge of such unknown quantities based on knowledge of their rates of change (derivatives). Key areas of focus of the course include Concepts, Techniques and Application of Integration to Business and related fields.
