Sum rule. For any functions f and g, d dx [f(x) + g(x)] = d dx [f(x)] + d dx [g(x)] . In words, the derivative of a sum is the sum of the derivatives.

In order to find a sum using sigma notation, we have to substitute the set of numbers (index) starting at the lower limit and ending at the upper limit of summation into the function part of the summation and add all of the found values.

Unpacking the meaning of summation notation This is the sigma symbol: ?. It tells us that we are summing something.

Sigma notation is essentially a shortcut way to show addition of series or sequences of numbers. It's based on the upper case Greek letter S, which indicates a sum. If the series is multiplied by a constant, you can find the sum of the series, then multiply the answer by the constant.

The symbol ? (sigma) is generally used to denote a sum of multiple terms. This symbol is generally accompanied by an index that varies to encompass all terms that must be considered in the sum. For example, the sum of first whole numbers can be represented in the following manner: 1 2 3 ?.

A series is the sum of the terms in a sequence. A series is often expresses in summation notation (also called sigma notation) which uses the capital Greek letter , sigma. Example: ? n = 1 5 n = 1 + 2 + 3 + 4 + 5 = 15 . Beneath the sigma is the index (in this case ) which tells us what value to plug in first.

Sigma notation is essentially a shortcut way to show addition of series or sequences of numbers. It's based on the upper case Greek letter S, which indicates a sum. If the series is multiplied by a constant, you can find the sum of the series, then multiply the answer by the constant.

The symbol ? indicates summation and is used as a shorthand notation for the sum of terms that follow a pattern.

The symbol ? (capital sigma) is often used as shorthand notation to indicate the sum of a number of similar terms. Sigma notation is used extensively in statistics.
