- Written By: Summation, in physiology, the additive effect of several electrical impulses on a neuromuscular junction, the junction between a nerve cell and a muscle cell. Individually the stimuli cannot evoke a response, but collectively they can generate a response. Successive stimuli on one nerve are called temporal summation; the addition of simultaneous stimuli from several conducting fibres is called spatial summation.

summation (sum) An example is 1/1 + 1/2 + 1/3. This becomes awkward when the number of terms is large. When a summation has infinitely many terms, the terms must occur in a definable sequence. This sequence is not always clear when the terms are simply listed and separated by + symbols.

What does the difference mean in math? , taught undergraduate tutorials since 2008. Sum is to difference as addition is to subtraction. There is a similar relationship between product and quotient, with respect to multiplication and division. The sum of [math]a[/math] and [math]b[/math] is obtained by finding the value of [math]a+b[/math]. The difference of [math]a[/math] and [math]b[/math] is obtained by finding the value of [math]a-b[/math].

Sequences When we sum up just part of a sequence it is called a Partial Sum. But a sum of an infinite sequence it is called a Series (it sounds like another name for sequence, but it is actually a sum). See Infinite Series.

Product (mathematics) Product (mathematics) In mathematics, a product is a number or a quantity obtained by multiplying two or more numbers together. For example: 4 × 7 = 28 Here, the number 28 is called the product of 4 and 7. The product of 6 and 4 will be 24, because 6 × 4 = 24.

Impulse (physics) In classical mechanics, impulse (symbolized by J or Imp) is the integral of a force, F, over the time interval, t, for which it acts. Since force is a vector quantity, impulse is also a vector in the same direction.Impulse applied to an object produces an equivalent vector change in its linear momentum, also in the same direction.he term impulse is also used to refer to a fast-acting force or impact. This type of impulse is often idealized so that the change in momentum produced by the force happens with no change in time.

Definitions &Translations Sequence. In mathematics, informally speaking, a sequence is an ordered list of objects. Like a set, it contains members. The number of ordered elements is called the length of the sequence. Unlike a set, order matters, and exactly the same elements can appear multiple times at different positions in the sequence.

Glossary of physics An average is a value that acts as a good representative of a set of numbers. Mathematically, the average is the sum of all values, divided by the number of values … there are. This is known as the arithmetic mean. There are also two other forms of average, other than the arithmetic mean.

Sequences and Series This section covers the basics of this summation notation. Summation is the operation of adding a sequence of numbers, the result being their sum or total. If numbers are added sequentially from left to right, any intermediate result is a partial sum, prefix sum, or running total of the summation.

Mathematical Notation Summation notation is used to compactly represent a sum of numbers. For example, suppose we want to compactly write the following sum, 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15. Sums of numbers, such as the one above, are often called series.
