For All Notes of (B.Sc , B.S Honors Associate Degree Program) of Mathematics Contact: +923008810640 ( Qamar Islam) In this Lecture we have discussed the following Important Things Group Theory 1) SUBGROUP 2) Trivial and Non-Trivial Subgroups 3) Theorem: Let H be a Subset of (G,.) Then H is a group of (G,.) Iff (i) For every h₁,h₂ ∈ H ⇒ h₁.h₂ ∈ H (ii) For every h ∈ H ⇒ h⁻¹ ∈ H 4) Theorem: Let H be a Subset of (G,+) Then H is a group of (G,+) Iff (i) For every h₁,h₂ ∈ H ⇒ h₁+h₂ ∈ H (ii) For every h ∈ H ⇒ -h ∈ H Mathematical Method For (B.Sc , B.S Honors Associate Degree Program) To study more exciting lectures For (B.Sc , B.S Honors Associate Degree Program), please follow the following link: Mechanics :    • Ch# 5(Friction |What is Friction, Angle of...      • Ch# 2 Composition of Forces  |Magnitude of...      • Ch#11|Air Resistance Proportion to the Squ...      • Ch# 10 Motion Of Projectile | Basic Concep...      • Ch# 7 Kinematics | Velocity and Accelerati...      • Ch# 8 Rectilinear Motion | Motion with con...   Mathematical Method :    • Ch# 9 | Degree and Order of Differential E...      • Ch# 10 Differential Equations of Higher Or...   Mathematical Method by SM Yusuf
