2 Session Differentiation - 2

3 Session Objectives  Fundamental Rules, Product Rule and Quotient Rule  Differentiation of Function of a Function  Differentiation by Trigonometric Substitutions  Differentiation of Implicit Functions  Class Exercise

4 Fundamental Rules

5 Example-1 Differentiate the following:

6 Solution Differentiating y with respect to x, we get

7 Product Rule Ifand are differentiable functions, then

8 Example-2 Differentiating w.r.t. x, we get Differentiate: w.r.t. x. Solution Let y =x 2 sinxlogx

9 Quotient Rule Ifand are differentiable functions and, then

10 Example-3 Differentiate: w.r.t. x. Solution: Differentiating w.r.t. x, we get

11 Differentiation of Function of a Function Note: If and, then If ƒ(x) and g(x) are differentiable functions, then ƒog is also differentiable (Chain Rule)

12 Example-4 Differentiatew. r. t. x. Solution: Differentiating y w.r.t. x, we get

13 Example-5

14 Continued

15 Trigonometric Substitutions

16 Example-6 Putting x 2 = cos2 Solution:

17 Continued Differentiating y w.r.t. x, we get

18 Example-7

19 Continued

20 Differentiation of Implicit Functions y is not expressible directly in terms of x

21 Example-8 We have xy 3 – yx 3 = x Solution:

22 Solution Cont.
