## FAQs on Examples : Approximations Video Lecture - Mathematics (Maths) Class 12 - JEE

 1. What are some common methods used for approximations in mathematics?
Ans. Some common methods used for approximations in mathematics include the Taylor series expansion, linear interpolation, and numerical methods such as Newton's method and the bisection method.
 2. How are approximations useful in real-world applications?
Ans. Approximations are useful in real-world applications as they allow us to estimate values or solve problems when exact solutions are difficult or time-consuming to obtain. They are widely used in engineering, physics, finance, and many other fields.
 3. Can approximations be used to solve non-linear equations?
Ans. Yes, approximations can be used to solve non-linear equations. Methods like Newton's method and the bisection method are commonly used to find approximate solutions for non-linear equations by iteratively refining the estimate until a satisfactory solution is obtained.
 4. Are there any limitations to using approximations in calculations?
Ans. Yes, there are limitations to using approximations in calculations. Depending on the method used, the accuracy of the approximation may vary, and in some cases, the error may accumulate over multiple calculations. It is important to assess the level of precision required for a particular problem and choose an appropriate approximation method accordingly.
 5. How can I determine the accuracy of an approximation?
Ans. The accuracy of an approximation can be determined by comparing it to the exact solution, if available. Alternatively, it can be assessed by calculating the error, which is the difference between the approximation and the exact value. Different methods may have different measures of error, such as absolute error or relative error, which help in evaluating the accuracy of the approximation.
