Can someon show me how to do one of these problems step by step so I have an idea of how to work these problems. I do not know what to do.

R1 = {(a, b) R^2 | a > b}, the "greater than" relation

R2 = {(a, b) R^2 | a>b}, the "greater than or equal to" relation

R3 = {(a, b) R^2 | a < b}, the "less than" relation

R4 = {(a, b) R^2 | a<b}, the "less than or equal to" relation

R5 = {(a, b) R^2 | a = b}, the "equal to" relation

R6 = {(a, b) R^2 | a b}, the "equal to" relation

Find:

a.) R1 o R1

b.) R1 o R2

c.) R1 o R3

d.) R1 o R4

e.) R1 o R5

f.) R1 o R6

g.) R2 0 R3

h.) R3 o R3
