Comprendre les Sommes

Third video this month, this time tackling sums and sigma notation. We cover the important properties: index change, telescoping/telescoping sums, etc., and we discuss the usual sums you need to know, with a short application exercise at the end. This video is the last one I had in mind for the beginning of the channel, and I'll probably be taking a break for a few weeks to focus on my upcoming midterms. I hope you found it useful, and I wish all the bgs who have read so far a good S2 😎 --DISCORD--   / discord   My social networks: 🕊️ Twitter/X: http://bit.ly/3QdT2Hi 📸 Instagram: https://bit.ly/4hy1vB0
