In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series or any expression; it is usually a number, but may be any expression.

If the syncope is prolonged, it can trigger a seizure. You may suffer from a simple fainting spell due to anxiety, fear, pain, intense emotional stress, hunger, or use of alcohol or drugs. Most people who suffer from simple fainting have no underlying heart or neurological (nerve or brain) problem.
Fainting, which is also called syncope, can be caused by many different things. Sometimes a specific cause for fainting cannot be found. A sudden drop in your blood pressure can cause you to faint. Sometimes your heart rate and blood vessels canât react fast enough when your bodyâs need for oxygen changes. This is very common among older people and in people who have certain health conditions, such as diabetes. Fainting can happen when: 1  You stand up too fast. 2  You work or play hard, especially if itâs very hot. 3  You begin to breathe too fast (called hyperventilating). 4  You get very upset. Being upset can affect the nerves that control your blood pressure. 5  Youâre taking medicine for high blood pressure.
