What are applications of Integrals?

We have learned formulas to calculate areas of various geometric shapes in geometry, including triangles, rectangles, trapezoids, and circles. These formulas are fundamental to many real-life problems in applications of mathematics. Formulas for elementary geometry allow us to compute areas of many simple figures. However, they are insufficient for calculating the areas surrounded by curves. For that, we will need some concepts of integral calculus.

In Chapter 7 above, we studied the area bounded by the curve y = f (x), ordinate x = a, x = b, and the x-axis, calculating the definite. In this chapter, we will study a specific application of integrals to find the area under simple curves, the area between lines and arcs, under parabola, and ellipse (standard size only). We will also take care to find the area delimited by these curves.



How do we find Area under the curve?

In Class 12 of Mathematics Chapter 7, we studied the definite integral as the limit of a sum and how to evaluate the definite integral using the fundamental principle of calculus. Now, let us consider an easy and intuitive way to find the area bounded by the curve y = f (x), the x-axis, and the ordinate x = a and x = b. We can think of the area under the curve as having a large number of very thin vertical stripes.

Consider an arbitrary strip of height y and width dx, then dA (area of the initial strip) = ydx, where, y = f (x). This region is called the primary region and is located in an unconstrained position within this region that is specified by some value of x between x and a. We can think of the total area A of the area between the x-axis, as a result of connecting the primary areas of thin strips with the area along x = a, x = b, and the curve y = f (x).
