FAQs on Application of Integrals: JEE Mains Previous Year Questions (2021-2024) - Mathematics (Maths) for JEE Main & Advanced

1. What is the application of integrals in JEE mains?
Ans. The application of integrals in JEE mains involves using integration techniques to solve problems related to areas, volumes, and other physical quantities. It helps in finding the area under curves, calculating the displacement, and determining the rate of change of quantities.
2. How are integrals used to find the area under curves in JEE mains?
Ans. Integrals are used to find the area under curves in JEE mains by calculating the definite integral of a function over a given interval. The area under a curve can be determined by integrating the function and evaluating it within the specified interval.
3. Can integrals be used to calculate the volume of solids in JEE mains?
Ans. Yes, integrals can be used to calculate the volume of solids in JEE mains. By considering the cross-sections of a solid and integrating them over a given interval, the volume of the solid can be determined. This technique is known as the method of cross-sections.
4. How are integrals applied to calculate displacement in JEE mains?
