# NCERT Solutions Class 12 Maths Chapter 8 Application of Integrals

NCERT solutions for class 12 maths chapter 8 application of integrals is a continuation of the previous chapter where kids were introduced to the topic of integration and how to solve questions based on different methods. Students have learned formulas to calculate areas of various geometrical figures including triangles, rectangles, trapeziums, and circles. Such elementary formulas are fundamental in the applications of mathematics to many real-life problems. However, when it comes to calculating the areas enclosed by curves this technique fails. To determine the areas under a curve we need integral calculus. The NCERT solutions for class 12 maths chapter 8 focuses on a specific application of integrals to find the area under curves. These curves could be simple or complex like circles, parabolas, hyperbolas, etc.

In chapter 7 children have studied definite integrals as the limit of a sum and how to evaluate these integrals using the Fundamental Theorem of Calculus. NCERT solutions class 12 maths chapter 8 uses this concept to give students an easy method of calculating the area under curves. The area under the curve can be thought of as being composed of a large number of very thin vertical stripes. By integrating this region between some specific limits we can now determine the complete area required. NCERT Solutions Chapter 8 Application of Integrals uses many real-life examples to give kids a better understanding of integration. It is an amazing lesson that shows the practical implications of this topic. In this article, we will explore the variety of examples, formulas, and theories in-depth to help students build a robust mathematical foundation, download the exercises provided in the links below.

## NCERT Solutions for Class 12 Maths Chapter 8 PDF

Integral Calculus is related to the method of exhaustion developed by Eudoxus (440 B.C.) and Archimedes (300 B.C.). This method arose as part of the solution of problems on calculating areas of plane figures, surface areas, and volumes of solid bodies. In 1665, Newton began his work on Calculus leading to the formation of concepts as we know them today. The NCERT solutions class 12 maths chapter 8 has several tips, tricks, and interesting facts to help students break the monotony while studying as well as develop a mathematical foundation that will carry them through their careers. Given below are the exercise-wise links to the PDF files of the solutions:
