I'm facing problem how to visualise vevtors when our sir teaches... what exactly are vectors how do they look like... how can we easily understand these properties such as rings etc

VECTORS

A vector is something which has magnitude and direction.

For example, Speed is a scalar because it is just a number without direction.

Velocity is always in a certain direction, so it is a vector.

At an abstract level, a Vector is an ordered sequence of numbers.

For example: (4, 5, 7) is a vector, as is (5, 9, 8 1, 2).

Have a look at: vector: Definition, Synonyms and Much More from Answers.com (http://www.answers.com/topic/vector?cat=health)


1. A quantity, such as velocity, completely specified by a magnitude and a direction.
2. A one-dimensional array.
3. An element of a vector space.
