    Equation solving is an art, and the proof by recurrence relation proves this. Just amazing

    Sir just a question.
    If I watch compendium of a chapter, do I need to watch symposium as well? Im using cengage and compendium series for theory and practice for advanced. Are the questions in compendium series on the level of advanced?

    5:55 when we place remaining n-1 in n-1 places are we not counting the cases when they can come in their right place??
    We have to dearrange the n-1 objects as only one object can come in ryt place.. Sir could u please clear my doubt

      Yes you are right. They could come to their original places but that's why we are using Inclusion and Exclusion principle which will remove all those who are on their original place till the end. That's the beauty of I&E Principle. I think you need more clarity of this principle.
