#### Class 12 Maths Exercise 5.1 Solutions in Videos

#### Class 12 Maths Exercise 5.2 Solutions in Videos

#### Class 12 Maths Exercise 5.3 Solutions in Videos

- The main points of the chapter are continuous functions, algebra of continuous functions, differentiation and continuity, chain rule, rules for derivative of inverse functions, derivative of implicit function, parametric and logarithmic functions. Second order derivatives, mean value theorems (LMV) and Rolle’s Theorem.
- Calculus (differentiability) deals with related variables and constants. In differential calculus we investigate the way in which ‘one quantity varies when the other related quantity is made to vary’. We find the rate of change (in Application of derivatives) one variable quantity relative to another variable. The relation between a function and its derivative is same as between displacement of a particle and its velocity.
- The derivative of f(x) at x = a is represented by the slope (gradient) of the tangent to the curve y = f(x) at the point P[a, f(a)].

##### ROLLE’S THEOREM

Let f be a real function defined in the closed interval [a, b] such that

(i) f is continuous in the closed interval [ a, b ]

(ii) f is differentiable in the open interval ( a, b )

(iii) f (a) = f (b)

Then f'(c) = 0, where c lies in (a, b).

###### MEAN VALUE THEOREM

Let f be a real valued function defined on the closed interval [a, b] such that

(a) f is continuous on [a, b], and

(b) f is differentiable in (a, b)

Then there exists a point c in the open interval (a, b) such that f ‘(c) = [f (b) – f (a)]/[b – a]

##### Which exercise of chapter 5 of class 12th Maths has the least number of sums?

Chapter 5 of class 12th Maths has nine exercises:

- In the first exercise (Ex 5.1), there are 20 examples (examples 1 to 20) and 34 questions.
- In the second exercise (Ex 5.2), there are three examples (examples 21, 22, 23) and ten questions.
- The third exercise (Ex 5.3) has four examples (examples 24, 25, 26, 27) and 15 questions.
- The fourth exercise (Ex 5.4) contains two examples (examples 28, 29) and ten questions.
- There are four examples (examples 30, 31, 32, 33) and 18 questions in the fifth exercise (Ex 5.5).
- In the sixth exercise (Ex 5.6), there are four examples (examples 34, 35, 36, 37) and 11 questions.
- In the seventh exercise (Ex 5.7), there are four examples (examples 38, 39, 40, 41) and 17 questions.
- The 8th exercise (Ex 5.8) has two examples (examples 42, 43) and 6 questions.
- The last (Miscellaneous) exercise has five examples (examples 44, 45, 46, 47, 48) and 23 questions.

So, the 8th exercise (Ex 5.8) has the least number of problems.

##### How many theorems and definitions are there in chapter 5 of Class 12th Maths?

There are seven theorems, one corollary, and four definitions in chapter 5, Continuity and Differentiability of class 12th Maths. All theorems, corollaries, and definitions are significant for the exams.

##### What are the main topics of chapter 5 of class 12th Maths NCERT?

The main topics of chapter 5 of class 12th Maths are:

- Continuity
- Algebra of continuous functions
- Differentiability
- Derivatives of composite functions
- Derivatives of implicit functions
- Derivatives of inverse trigonometric functions

##### Is there any topic to revise before starting chapter 5 of 12th standard Maths?

Before starting chapter 5 (Continuity and Differentiability) of 12th standard Maths, students should revise chapter 13 (Limits and Derivatives) of grade 11th Maths. Chapter 13 of class 11th Maths works as a base for chapter 5 of class 12th Maths.
