Solve all the questions using quotient rule. ………(1)

Question 1: Differentiate 2x/x

Solution:

Here u = 2x and v = x

u’ = d/dx (2x) = 2x log 2

v’ = d/dx (x) = 1

(1)=> Question 2: Differentiate log x/x

Solution:

Here u = log x and v = x

u’ = d/dx (log x) = 1/x

v’ = d/dx (x) = 1

(1)=> Question 3: Differentiate ex/(1+x)

Solution:

Here u = ex and v = 1+x

u’ = d/dx (ex) = ex

v’ = d/dx (1+x) = 1

(1)=> Question 4: Differentiate ex/(1+x2)

Solution:

Here u = ex and v = 1+x2

Using Quotient rule, we have Question 5: Differentiate Solution:

Here u = 2x2 – 4 and v = 3x2 + 7

Using Quotient rule, we have Question 6: Differentiate Solution:

Here u = x2 +3x – 1 and v = x + 2

Using Quotient rule, we have Question 7: Differentiate Solution:

Here u = x2 – 1 and v = x2 + 7x + 1

Using Quotient rule, we have Question 8: Differentiate Solution:

Here u = 5x2 +6x + 7 and v = 2x2 + 3x + 4

Using Quotient rule, we have Question 9: Differentiate Solution:

Here u = x and v = a2 + x2

Using Quotient rule, we have Question 10: Differentiate x4/sinx

Solution:

Here u = x4 and v = sinx

Using Quotient rule, we have Question 11: Differentiate Solution:

Here u = √a + √x and v = √a – √x

Using Quotient rule, we have Question 12: Differentiate cosx/log x

Solution:

Here u = cos x and v = log x

Using Quotient rule, we have ## Access other exercise solutions of Class 11 Maths Chapter 28 Differentiation
