Introduction

The application of integrals is a vast and essential part of calculus, playing a crucial role in various scientific, engineering, and mathematical fields. Integral calculus is the study of representing functions as the limit of sums, which is fundamentally the process of accumulation. This concept allows for the calculation of areas, volumes, and other quantities that arise from aggregating infinitesimal data points..Throughout this chapter, emphasis is placed on elucidating critical cbse class 12 maths application of integrals.

What are Application of the Integrals?

Applications of integrals are vast and varied, spanning across many fields.
Area under a Curve: One of the fundamental applications of integrals is finding the area under a curve. This is used extensively in physics and engineering to determine distances, areas, and other spatial properties.
Volume Calculation: Integrals are used to calculate the volume of three-dimensional objects, especially those with irregular shapes. This is crucial in fields like manufacturing, architecture, and civil engineering.
Each of these applications involves integrating functions over specific intervals to calculate quantities that are not easily measurable or observable directly.

Class 12 Application of the Integrals Important Questions and Answers

Q1. The area of the region bounded by the curve x² = 4y and the straight line x = 4y – 2 is
Options
(a) katex is not defined (b)katex is not defined (c)katex is not defined (d)katex is not defined

Ans. (d)katex is not defined Explanation:
For the curves katex is not defined the points of intersection are x = -1 and x = 2.
Hence, the required area, A = katex is not defined Now, integrate the function and apply the limits, we get
katex is not defined

Q2: The area enclosed between the graph of katex is not definedand the lines x = 0, y = 1, y = 8 is
Options
(a) 7
(b) 14
(c) katex is not defined (d) None of these

Ans. (c) katex is not defined

Explanation:
Given curve,katex is not defined Hence, the required area,
katex is not defined Now, apply the limits, we get
katex is not defined

Q3. The area of the region bounded by the curve y² = x, the y-axis and between y = 2 and y = 4 is?

Explanation:
Given: katex is not defined Hence, the required area, katex is not defined

Q4. Area bounded by the curve y = sin x and the x-axis between x = 0 and x = 2π is?

Explanation:
Required Area, A = katex is not defined Now, substitute the limits, we get
A= 4 sq. units.

Q5: The area of the region bounded by the circle x² + y² = 1 ?

Explanation:
Given circle equation is katex is not defined whose centre is (0, 0) and radius is 1.
Therefore, katex is not defined Hence, the required area,katex is not defined Now, integrate the function and apply limits, we get
katex is not defined A = π sq. units

Frequently Asked Questions

Ans: Integrals find applications in various fields, such as physics, engineering, economics, and biology. They are used to calculate areas, volumes, work done, center of mass, and more.
Ans: To find the area between curves, you typically calculate the definite integral of the absolute difference between the functions representing the curves within the specified bounds.
Ans: Integrals play a crucial role in finding volumes of solids obtained by rotating a region bounded by curves around a specific axis. This process involves slicing the solid into infinitesimally thin discs or washers and summing their volumes using integrals.
Ans: In physics, integrals are applied to find work done by a force. For instance, in the context of moving an object against a force, work done is calculated by integrating the product of force and displacement over a specified path.
Ans: Integrals help determine the center of mass by considering the weighted average of the positions of all the constituent particles or components in a system. Integrating mass distributions allows for the calculation of the center of mass along different axes.
