## Preparation for Class 12 with RD Sharma Solutions

## FAQs on RD Sharma Solutions for Class 12 Maths Chapter 22 - Differential Equations - Free PDF Download

**1. In calculus, what is a differential equation?**

In mathematics, an equation that relates one or more functions and their derivatives is a differential equation. In implementations, the functions usually represent physical quantities, the derivatives represent their change rates, and the relationship between the two is defined by the differential equation.

**2. What are the two forms of equations for differentials?**

There are 2 forms of differential equations, a differential equation that includes partial derivatives is a partial differential equation. A differential equation that does not include partial derivatives is an ordinary differential equation.

**3. Why are we using differential equations?**

Ordinary differential equations applications in real life are used to measure the movement or flow of energy, the rotation of an object to and fro like a pendulum, and to illustrate thermodynamics principles. They are often used, in medical terminology, to verify the growth of diseases in graphic representation.

**4. Why is R D Sharma Solutions for Class 12 important for board exams?**

RD Sharma Solutions for Class 12 is important for a board examinee as it gives all the correct answers to all the questions given in the RD Sharma book. Since students will be learning the concepts in the book just in class 12, it will be difficult for them to understand if they have got the answers to the questions that they have solved, correct or not. These solution sets will help the students judge their performances before the board exams.

**5. How much time should a Class 12 student devote to Maths?**

Ideally, students of Class 12 should practice Maths every day before their exam. Maths is not a subject to learn; it is a subject of practice. Students might have understood and grasped all the concepts that are given in their syllabus, but a lack of practice will lead to a lack of clarity and accuracy in their exams. They might forget whatever they have learnt and practised. So, it's good to practice Maths at least two hours a day before exams.
