NCERT Solutions for Class 12 Maths Chapter 8 Exercise 8.1 Application of Integrals - PDF Download

1. Area under Simple Curves

Here, you will learn the easy and intuitive way of finding the area bounded by the curve y = f(x), x-axis and the ordinates x = a and x = b. To find the curve area using integration is an arbitrary strip of height y and width dx. This area is called the elementary area which is located at an arbitrary position within the region which is specified by some value of x between a and b. 

• The area of the region bounded by the curve y = f (x), x-axis and the lines x = a and x = b (b > a) is given by the formula: Area = $\int_a^b y d x=\int_a^b f(x) d x$ . 

• The area of the region bounded by the curve x = (y), y-axis and the lines y = c, y = d is given by the formula: Area = $\int_c^d x d y=\int_c^d \phi(y) d y$ .
