## NCERT Solutions for Class 12 Maths Chapter 9 Differential Equations Ex 9.6

**Find the general solution of the following differential equations in Q.1 to 12**

**Ex 9.6 Class 12 Maths Question 1.**

**Solution:**

Given equation is a linear differential equation of the form ;

Here, P = 2, Q = sin x

**Ex 9.6 Class 12 Maths Question 2.**

**Solution:**

Here P = 3,

which is required equation

**Ex 9.6 Class 12 Maths Question 3.**

**Solution:**

**Ex 9.6 Class 12 Maths Question 4.**

**Solution:**

Here, P = secx, Q = tanx;

= sec x + tan x

i.e., The solu. is y.× I.F. = ∫Q × I.F. dx + c

or y × (secx+tanx) = ∫tanx(secx+tanx)dx+c

Reqd. sol. is

∴ y(secx + tanx) = (secx + tanx)-x + c

**Ex 9.6 Class 12 Maths Question 5.**

**Solution:**

⇒ integrating factor =

**Ex 9.6 Class 12 Maths Question 6.**

**Solution:**

Here P = and Q = x logx

**Ex 9.6 Class 12 Maths Question 7.**

**Solution:**

**Ex 9.6 Class 12 Maths Question 8.**

(1+x²)dy+2xy dx = cotx dx(x≠0)

**Solution:**

(1+x²)dy+2xy dx = cotx dx

**Ex 9.6 Class 12 Maths Question 9.**

**Solution:**

**Ex 9.6 Class 12 Maths Question 10.**

**Solution:**

**Ex 9.6 Class 12 Maths Question 11.**

**Solution:**

**Ex 9.6 Class 12 Maths Question 12.**

**Solution:**
