**Introduction:** Class 12 Maths chapter 5 notes are concerning continuity and differentiability. In continuity and differentiability, Class 12 notes include finding continuity and differentiability nothing but finding the limits and differentiating. This Class 12 Maths chapter 5 notes contains the following topics: continuity at a point, continuity in the interval, few standard limits notations, differentiability, right-hand derivative, left-hand derivative, rules of differentiation like sum, difference, product, quotient, chain rules, second-order derivatives, standard formulas, Rolle’s theorem, Mean value theorem and many more.

Notes for Class 12 Maths chapter 5 also contain standard formulas that are to be memorised for the implementation in problems. NCERT Class 12 Math chapter 5 contains a detailed explanation of topics, theorems, examples, exercises. By going through the document students can cover all the topics that are in NCERT Notes for Class 12 Math chapter 5 textbook. It also contains examples, exercises, a few interesting points and most importantly contains FAQs that are frequently asked questions by students which can clarify many other students with the same doubt.

**DEFINITION:** suppose f be a real function, c be a point in the domain of function f in the range of real numbers. f is said to be continuous if it satisfies

x→c fx=f(c)

Theoretical: If the left-hand side limit, right-hand side limits are equal, and x=c then function f is said to be continuous else not continuous.

**DEFINITION 2:** A function f is said to be continuous if it is continuous at every point in domain f.

Continuity of a:

**Algebra of continuous functions:**

f and g be two real numbers that are continuous and real at point c, then

a) f + g is continuous at x = c

b) f-g is continuous at x = c

c) f. g is continuous at x = c

d) fg is continuous at x=c and g(c) ≠ 0

Proof:

**From equation a :**

f + g is said to be continuous at x = c

=

= f(c) + g(c)

= (f+ g) (c)

**Hence proved that it is continuous.**

suppose f be a real function, c be a point in the domain of function f in the range of real numbers. f is said to be differentiable if it satisfies:

Derivative of f(x) is given by f’(x)

RIGHT HAND DERIVATIVE:

LEFT HAND DERIVATIVE:

Sum and difference rule: let y = f(x) ± g(x)

Product rule: Let y = f(x) g(x)

Quotient rule: Let y = f(x)/g(x); g(x) ≠ 0

Chain rule: Let y = f(u) and u = f(x)

Differentiation of Functions in Parametric Form: Relationship between two values x and y that are expressed in the forms x = f(t), y = g(t) is called to be in parametric form when,

Second-order Derivative: Deriving First order derivative will result in a second-order derivative.

Let f : [a, b] → R be a real number and is continuous on [a, b] satisfies following:

a)differentiable in the interval (a, b) so that f(a) = f(b); a, b are real numbers. Then,

b) there will be at least one number c in (a, b) that satisfies the condition f'(c) = 0.

This is called Rolle’s Theorem.

Let f : [a, b] → R be a real number that is continuous in the interval [a, b] satisfies the following:

a) differentiable in the interval (a, b). Then,

b) there will be at least one number c in the interval (a, b) that satisfies the condition

This is called the mean value theorem.

With this topic we conclude NCERT class 12 chapter 5 notes.
