- Sum[List]
- Calculates the sum of all list elements.
- Note: This command works for numbers, points, vectors, text, and functions.
- Example:
- Sum[{1, 2, 3}] gives you the number a = 6.
- Sum[{x^2, x^3}] gives you f(x) = x2 + x3.
- Sum[Sequence[i,i,1,100]] gives you the number a = 5050.
- Sum[{(1, 2), (2, 3)}] gives you the point A = (3, 5).
- Sum[{(1, 2), 3}] gives you the point B = (4, 2).
- Sum[{"a","b","c"}] gives you the text "abc".
- Sum[List, Number n of Elements]
- Calculates the sum of the first n list elements.
- Note: This command works for numbers, points, vectors, text, and functions.
- Example: Sum[{1, 2, 3, 4, 5, 6}, 4] gives you the number a = 10.
