Chapter 5 Maths Class 12 Formulas and Theorems 

Go through Class 12 Maths Continuity and Differentiability formulas and theorems:

Definition of Continuity:

(i) The continuity of a real function (f) on a subset of the real numbers is defined when the function exists at point c and is given as-

Lim

x→c

f(x)=f(c)

(ii) A real function (f) is said to be continuous if it is continuous at every point in the domain of f.

Consider a function f(x), and the function is said to be continuous at every point in [a, b] including the endpoints a and b.

Continuity of “f” at a means,

Lim

x→a

f(x)=f(a)

Continuity of “f” at b means,

Lim

x→b

f(x)=f(b)

Differentiability formula

Assume that if f is a real function and c is a point in its domain. The derivative of f at c is defined by 0

The derivative of a function f at c is defined by-

Lim

h→0

f(x+h)–f(c)

h

Theorem 1: Algebra of continuous functions:

If the two real functions say f and g, are continuous at a real number c, then

(i) f + g is continuous at x=c.

(ii) f – g is continuous at x=c.

(iii) f. g is continuous at x=c.

(iv)f/g is continuous at x=c, (provided g(c) ≠ 0).

Theorem 2:  Suppose f and g are real-valued functions such that (f o g) is defined at c. If g is continuous at c and if f is continuous at g (c), then (f o g) is continuous at c.

Theorem 3: If a function f is differentiable at a point c, then it is also continuous at that point.

Theorem 4 (Chain Rule): Let f be a real-valued function that is a composite of two functions u and v; i.e., f = v o u.

Suppose t = u(x) and if both dt/dx and dv/dt exist, we have df/dx = (dv/dt). (dt/dx)

Theorem 5:

(1) The derivative of ex with respect to x is ex;  i.e., d/dx(ex) = ex.

(2) The derivative of log x with respect to x is 1/x.

i.e., d/dx(log x) =1/x.

Theorem 6 (Rolle’s Theorem): Let f : [a, b] → R be continuous on [a, b] and differentiable on (a, b), such that f(a) = f(b), where a and b are some real numbers. Then there exists some c in (a, b) such that f'(c) = 0.
