Euler’s Phi (∅) Function | Euler’s Theorem in Group Theory

This video tutorial provides proof of Euler’s Phi Function (Euler’s ∅ Function) and Euler’s Theorem. The Euler’s phi function and Euler’s theorem is explained with the help of plenty of solved problems. This video tutorial is most suitable for the students of BSc Maths, Engineering Mathematics, and students preparing for CSIR NET, IIT JAM, and competitive exams.
