In mathematics, a vector (from the Latin word "vehere" meaning "to carry") is a geometric entity that has magnitude (or length) and direction. Vectors can be added to other vectors according to vector algebra. Vectors play an important role in physics, engineering, and mathematics.

In mathematics, a vector (from the Latin word "vehere" which means "to carry") is a geometric object that has a magnitude (or length) and direction. A vector can be thought of as an arrow in Euclidean space, drawn from the origin of the space to a point, and denoted by a letter. The magnitude of the vector is the distance from the origin to the point, and the direction is the angle between the direction of the vector and the axis, measured counterclockwise.

the problem is finding the direction co sign and the directions and goes off selector halftimes ai plus de plus que First The magnitude ofthe this factor is a culture tough force. One bus line. It's justice. We caught you three away too, so they have to direction. Kasay's are sign now. Thought he quit you half over. Three over to this is food. Consign beta If he caught you two. Thirty. Thank you, Mama. It's their country to a third. So they have off is about seventy one degrees beta. It's for two comma, about forty eight degrees.
