NCERT Solutions for Class 12 Maths Chapter 1 Miscellaneous Exercise: Important Points to Remember

Students can go through some of the important points of Class 12 Maths Chapter 1 to learn more about the topics:

A binary operation ** on a set SS associates any two elements a,b∈Sa,b∈S to a unique element a*b∈Sa*b∈S.
Distributive over a binary operation∘∘on SS, if a*(b∘c)=(a*b)∘(a*c)a*(b∘c)=(a*b)∘(a*c) and (b∘c)*a=(b*a)∘(c*a)(b∘c)*a=(b*a)∘(c*a) for all a,b∈S
Commutative, ifa*b=b*aa*b=b*a for all a,b∈S
Types of relations
- (i) The identity relation, if every element of AA is related to itself only.
- (ii) Reflexive, if (a,a)∈R(a,a)∈R for all a∈Aa∈A
- (iii) Symmetric, if (a,b)∈R⇒(b, a)∈R(a,b)∈R⇒(b, a)∈R for all a,b∈Aa,b∈A
- (iv) Transitive, if (a,b)∈R(a,b)∈R and (b, c)∈R⇒(a,c)∈R(b, c)∈R⇒(a,c)∈R for all a,b,c∈A
Composition of functions and Invertible functions
- (i) If f:A→Bf:A→B is a bijection, then g:B→Ag:B→A is inverse of ff if f(x)=y⇒g(y)=xf(x)=y⇒g(y)=x or gof=IAgof=IA and fog=IBfog=IB
- (ii) Let f:A→Bf:A→B and g:B→Ag:B→A be two functions, If gof=IAgof=IA and ff is an injection, then gg is a surjection. And if fog=IBfog=IB and ff is a surjection, then gg is an injection.
- (iii) Let f:A→Bf:A→B and g:B→Cg:B→C be two functions, If gof: A→Cgof: A→C is onto, then g:B→Cg:B→C is onto And if gof:A→Cgof:A→C is one-one, then f: A→Bf: A→B is one-one.
