Fourier Series

I tried exploring the Fourier series a bit more (to learn DSP well). I found two wonderful references, which I must share.

Eric W. Weisstein. "Fourier Series." From MathWorld--A Wolfram Web Resource. The discussion of orthonognal functions is particularly insightful and so is the discussion on the Gibbs Phenomenon.

The second one is R W Hammings book on Numerical Analysis. I wish all books were written in the same simple manner this book adopts. After all, the "Purpose of computing is insight, not numbers"

I remember some of these details from my engineering days, but I wish I had access to these resources then.

Dynamic programming for the binomial coefficient

More fun things, this time with some visualisation of what happens when memoisation is used and what happens when we don't. I don'...
