Study Notes
Series
- A series is the sum of the terms of a sequence, which can be either finite or infinite.
Finite Series
- The sum of the first n terms of a sequence is denoted as S_n.
- S_n is calculated by adding the first n terms: T_1 + T_2 + T_3 + … + T_n.
Infinite Series
- An infinite series sums infinitely many terms of a sequence.
- The sum of an infinite series is denoted as S_∞.
Sigma Notation
- Sigma notation is a concise way to represent the sum of terms in a sequence.
- The summation symbol Σ (Greek letter S) is used to denote the sum.
- The general form of sigma notation is: ∑_{i=m}^{n} T_i = T_m + T_{m+1} + … + T_{n-1} + T_n.
Sigma Notation Components
- i is the index of summation.
- m is the lower bound (starting index).
- n is the upper bound (ending index).
- T_i is the term of the sequence at index i.
