Group Theory| Two Step Subgroup Test| Theorem on Subgroup and its proof| Theta Classes

In this lecture we are going to discuss about another theorem on subgroup which is used to check whether a given subset of a group is subgroup or not. This theorem is called two step subgroup test. First we will see statement and then we will prove the given theorem.
While proving if any part of lecture is not clear then do mention it in comment section.
Keep connected with Theta Classes to study various topics of higher mathematics.
