Sigma notation - mathcentreacuk
We can now see that k-th term is (−1)k 1/k, and that there are 100 terms, so we would write the sum in sigma notation as X100 k=1 (−1)k 1 k Key Point To write a sum in sigma notation, try to find a formula involving a variable k where the first term can be obtained by setting k = 1, the second term by k = 2, and so on Exercises 3
INTRODUCTION TO SIGMA NOTATION
Sigma notation is a way of writing a sum of many terms, in a concise 1 k + 1 Here, the index k takes the values 0, 1, 2, and 3 We’ll plug those each into 1 k+1
Introduction to Section 51: Sigma Notation, Summation
For each natural number k, we de ne p k(n) = Xn j=1 jk; for n = 1;2;::: Then p k(n) is a polynomial in n of degree k + 1, and its leading coe cient is 1 k + 1 In other words: Xn j=1 jk = nk+1 k + 1 + nkc k + n k 1c k 1 + :::nc 1 + c 0; where c 0;c 1;:::c k are some coe cients

Se lee: la sumatoria de los elementos a k desde k = n hasta k = m Nota: 1 Los límites superior e inferior de la sumatoria son constantes respecto del índice de la sumatoria 2 El límite inferior es cualquier número entero menor o igual que el límite superior; es decir, n m Ejemplo: Calcular: 5 k 3 (2k 1) Solución: 1(3)-1 k=3 2(4)-1 k=4

• Sigma algebras can be generated from arbitrary sets This will be useful in developing the probability space Theorem: For some set X, the intersection of all σ-algebras, Ai, containing X −that is, x ∈X x ∈Ai for all i− is itself a σ-algebra, denoted σ(X) This is called the σ-algebra generatedby X Sigma-algebra Sample Space, Ω
