** Answer: **

Given,

Now, differentiating both sides w.r.t. x,

Again, differentiating both sides w.r.t. x,

Substituting the values of y’ and y'' in the given differential equations,

y'' - y' = e ^{ x } - e ^{ x } = 0 = RHS.

Therefore, the given function is the solution of the corresponding differential equation.

** Answer: **

Given,

Now, differentiating both sides w.r.t. x,

Substituting the values of y’ in the given differential equations,

.

Therefore, the given function is the solution of the corresponding differential equation.

** Answer: **

Given,

Now, differentiating both sides w.r.t. x,

Substituting the values of y’ in the given differential equations,

.

Therefore, the given function is not the solution of the corresponding differential equation.

** Answer: **

Given,

Now, differentiating both sides w.r.t. x,

Substituting the values of y in RHS,

.

Therefore, the given function is a solution of the corresponding differential equation.

** Answer: **

Given,

Now, differentiating both sides w.r.t. x,

Substituting the values of y' in LHS,

.

Therefore, the given function is a solution of the corresponding differential equation.

** Answer: **

Given,

Now, differentiating both sides w.r.t. x,

Substituting the values of y' in LHS,

Substituting the values of y in RHS.

Therefore, the given function is a solution of the corresponding differential equation.

** Answer: **

Given,

Now, differentiating both sides w.r.t. x,

Substituting the values of y' in LHS,

Therefore, the given function is a solution of the corresponding differential equation.

** Answer: **

Given,

Now, differentiating both sides w.r.t. x,

y' + siny.y' = 1

y'(1 + siny) = 1

Substituting the values of y and y' in LHS,

** = (x + cosy) = y = RHS **

Therefore, the given function is a solution of the corresponding differential equation.

** Answer: **

Given,

Now, differentiating both sides w.r.t. x,

Therefore, the given function is a solution of the corresponding differential equation.

** Answer: **

Given,

Now, differentiating both sides w.r.t. x,

Substituting the values of y and y' in LHS,

Therefore, the given function is a solution of the corresponding differential equation.

** Answer: **

(D) 4

The number of constants in the general solution of a differential equation of order n is equal to its order.

** Answer: **

(D) 0

In a particular solution of a differential equation, there is no arbitrary constant.

Two examples are given before exercise 9.2 Class 12 Maths.

Hello student,

**
If you are planning to appear again for class 12th board exam with PCMB as a private candidate here is the right information you need:
**

- No school admission needed! Register directly with CBSE. (But if you want to attend the school then you can take admission in any private school of your choice but it will be waste of money)
- You have to appear for the 2025 12th board exams.
- Registration for class 12th board exam starts around September 2024 (check CBSE website for exact dates).
- Aim to register before late October to avoid extra fees.
- Schools might not offer classes for private students, so focus on self-study or coaching.

**
Remember
**
, these are tentative dates based on last year. Keep an eye on the CBSE website ( https://www.cbse.gov.in/ ) for the accurate and official announcement.
