AIt uses the Greek capital letter sigma
BIt uses a Greek lower-case letter sigma
CIt was named after a mathematician sigma
DIt uses the Latin letter S for a sum
Answer & Solution
Correct answer: A. It uses the Greek capital letter sigma
1. Summation notation compresses a long sum into a single symbol.
2. That symbol is the Greek capital letter sigma, which is why the notation carries the name.
3. Alongside the sigma sit the explicit formula for the terms and the first and last values of the index.
4. No mathematician of that name is involved, so the naming is purely about the symbol used.
