## FAQs on RD Sharma Class 12 Solutions Chapter 11 - Differentiation (Ex 11.5) Exercise 11.5

**1. Where can I find revision notes for Class 12 Differentiation?**

For Class 12 Maths Differentiation, Vedantu provided Revision Notes. The revision notes are designed by various subject experts and follow the latest exam pattern. These notes will help the students to learn all the various types of differential equations and an in-depth study about these equations. Relevant diagrams are also provided in the notes to help students to have a better understanding of the concept. Going through these notes thoroughly will help the students to even attempt the complicated exams easily and with much more confidence in the exam.

**2. What are the real-life applications of all the four rules of differentiation- chain rule, sum and difference rule, product rule and quotient rule?**

In Engineering, the chain rule has broad applications-

To determine the increase and decrease in a function.

To calculate between two moving objects, the rate of change of distance.

It helps us to deduce the rate of change in the real world.

To determine the long distance between two points such as the distance between the sun and the earth.

To determine long heights such as the height of a mountain.

To determine how long the drug will take to enter your body.

To generate accounting reports in business

To determine the effect of price change in revenue

The quotient rule and the other rules can be used interchangeably but one example could be, given the volume of pool water and the rate of water flowing into the pool if you were filling a pool and you want to see how much the water has increase you can use the quotient rule.

**3. What is the difference between a derivative and a differential?**

The differential is one of the fundamental divisions of calculus. The differential is a subfield of calculus that deals with infinitesimal changes in varying quantities. Differential equations consist of unknown functions and their derivatives while a derivative of a function is a new function also called the rate function.

The differential is the function that represents the relationship between dependent and independent variables while the derivative is the function where the relationship between the variables is known.

**4. Are Vedantu’s RD Sharma Class 12 Solutions helpful?**

Vedantu designs all its solutions from the subject experts themselves and all the solutions are conceptually and methodologically. Most of the students who go for competitive exams prefer RD Sharma Class 12 Maths which has higher level questions as well and sometimes it becomes difficult for the students to solve.

Vedantu’s solutions are designed in such a way that they not only just answer the questions but help the students to make the conceptual understanding in a better manner.

**5. How to study differential equations?**

The most important part while studying differential equations is practice. Once the student learns all the differential equations it becomes very easy for the student to solve the questions. If the student faces any problem while solving any question or understanding any concept. Vedantu provides everything, be it revision notes or solved questions.
