do like that let's for,,,, big O
lets A=O(B) ie. A<=B
a) reflexive:
A<=A ........which is satisfied so reflexive
b) symmetric:
A<=B which is not implied to B<=A .............so not symmetric
c) transitive:
A<=B and B<=C which is implied A<=C..........so transitive
do same for omega and theeta notation
omega satisfied reflexive and transitive property
theeta satisfied reflexive, symmetric and transitive property
