Application of Integrals
Maps measure fields and ponds without counting squares. Chapter 8, Application of Integrals, of the NCERT Mathematics textbook for Class 12 shows how definite integrals give exact areas. You will find the area under a simple curve, the area between a curve and a line, and regions enclosed by parabolas, circles and ellipses in standard form. Sketching the region, finding intersection points and choosing horizontal or vertical strips are practised carefully, so area problems become a sequence of clear drawing and integration steps.
