What are the prerequisite to understand Generating Function?
I tried Rosen book, but I didn't get anything from it except the fact that there's some power series involvement in it.
Now, I don't know calculas at all. So, I don't know anything about Power series.
Then I tried watching this video of IIT MADRAS - Lecture 30 - Generating Functions but it has some serious audio/video lag and I'm not able to make much form this video!
SO, anyone tell me what are things required to understand Generating Function.
P.S - I studied Binomial Theorem Chapter from Class 11th Cbse as binomial expansions are used in generating function.
Please tell me, I'm unable to understand this topic at all.
Thanks
