**RD Sharma Class 12 Ex 11.6 Solutions Chapter 11 Differentiation**

**Question 1. If ****, prove that **

**Solution:**

We have,

⇒

Squaring both sides, we get,

y^{2} = x + y

**Question 2. If ****, prove that **

**Solution:**

We have,

⇒

Squaring both sides, we get,

y

^{2}= cos x + y⇒

**Question 3. If ****, prove that **

**Solution:**

We have,

⇒

Squaring both sides, we get,

y^{2} = log x + y

**Question 4. If **** , prove that **

**Solution:**

We have,

⇒

Squaring both sides, we get,

y^{2} = tan x + y

**Question 5. If **** , prove that **

**Solution:**

We have,

⇒ y = (sin x)^{y}

Taking log on both sides,

log y = log(sin x)^{y}

⇒ log y = y log(sin x)

**Question 6. If **** , prove that **

**Solution:**

We have,

⇒ y = (tan x)^{y}

Taking log on both sides,

log y = log(tan x)^{y}

⇒ log y = y log tan x

Differentiating with respect to x using chain rule,

Now,

**Question 7. If **** , prove that **

**Solution:**

We have,

⇒ y = u + v + w

where

Now,

Taking log on both sides,

Differentiating with respect to x,

Taking log on both sides,

Taking log on both sides

Using equation in equation (i), we get

**Question 8. If ****, Prove that **

**Solution:**

We have,

⇒ y = (cos x)^{y}

Taking log on both sides,

log y = log(cos x)^{y}

⇒ log y = y log (cos x)

Differentiating with respect to x using chain rule,
