## Important Topics NCERT Exemplar Class 12 Maths Solutions Chapter 8 – Application of Integrals

There are various strategies for calculations among which are differentiation, functions as well as integration. The use of Integrals is applied in different fields like Mathematics, Science, Engineering, and so forth. For the estimation of areas, we use significant integral equations.

**Area****covered by simple curve:**

In this section, you will get to know about the enclosed area by the curve by Leibnitz Rule, assessment and properties of definite integrals by substitution, integral functional properties, definition, and properties of the gamma function and Walli’s formula.

The area within bounded region by the curve were, y = f (x), x-axis and the lines x = a and x = b (b > a) is denoted by the formula:

**The area within the bounded region of a curve and a line:**

Here, you will get to know about various areas of a part bounded through a line and a circle, a line, and a parabola, a line, and an ellipse. The area of the bounded region by a curve was, x = Φ (y), y-axis and the lines y = c, y = d is given by the formula:

The area of the region confined between two curves was, y = f (x), y = g (x) and the lines x = a, x = b is given by the formula.

**The area between two curves**

This part of the exemplar problems in NCERT Exemplar for class 12 maths chapter 8 tells you about the area confined within two curves, area of curves given by polar equations, area of parametric curves.
